"It's a good thing Hector Bellerin has got all this pace, because at times Per Mertesacker can be a liability, in terms of speed. But I have to ask - why is Arsene Wenger persisting with Mesut Ozil? He's offered nothing since the World Cup. Give someone like Alex Oxlade-Chamberlain a go."

Top-of-the-table Burton Albion beat York at the weekend and now put their unbeaten League Two record on the line at AFC Wimbledon. Their hosts may be on a four-match winless streak but Burton have failed to beat the Dons in their last three meetings.

Fifth-placed Cheltenham suffered their first defeat of the season at the weekend and will be hoping to bounce back at home to eighth-placed Southend. The visitors ended a four-game winless run with a 2-0 win over Portsmouth on Saturday.

At the foot of the table, managerless Carlisle are still seeking their first win of the season and travel to New Meadow to take on seventh-placed Shrewsbury. The Cumbrians have picked up just one of their three points on the road this season and have conceded more goals than any team.

"Hector Bellerin, I've heard, has trained very well and has been given this opportunity. What a game to be given that opportunity! At some stage, people have to be thrown in. Ideally, Wenger would have had Debuchy and Chambers fit, but they're not. Hopefully the experience around him in the defence will help Bellerin along a bit."

If Liverpool boss Brendan Rodgers has his way, there will be no sign whatsoever of complacency from his side tonight.

"We want to be at the elite level and the Champions League is that," said Rodgers on Monday.

"We know Ludogorets are excited about coming to Anfield.

"We'll respect them like we would if we were playing Real Madrid. They play an open, attacking style and they'll come here with confidence."

Arsenal defender Hector Bellerin:, external Confidence is having all the hard work done.

Three changes for Arsenal from the side that started last Saturday's 2-2 draw with Manchester City.

In come Kieran Gibbs, Mikel Arteta and 19-year-old Hector Bellerin. Bellerin starts at right-back after Mathieu Debuchy is ruled out, with Calum Chambers confined to the bench after falling ill with tonsillitis.

Arteta anchors the midfield having overcome an ankle problem, while Dortmund's former Manchester United midfielder Shinji Kagawa features among the substitutes for the German club.

So who are these Bulgarian chancers lining up at Anfield tonight?

If you've never heard of Ludogorets Razgrad, you are entirely forgiven. The team were still playing as amateurs in the third tier of Bulgarian football last time Liverpool lined up in the Champions League.

Household names? Zero. The away side start as 16/1 outsiders to win tonight - but Liverpool won't take them lightly...

BBC Radio 5 live presenter Mark Pougatch: , externalIs this chap the first 'Hector' ever to play for Arsenal? And if he is, who'd thought he'd be Spanish and not an Englishman in 1890s?

Paul Day:, external Mertersaker marking someone called Immobile? Sounds right up his strasse. Come on the BFG!

Harry Partridge:, external Arsenal's starting line up is about as good as the same fixture last season, but the bench is much stronger this time around!

Olajide Jaio:, external After last time out with Aston Villa, I'm afraid for life without Sturridge at Liverpool.

"Canadian keeper Milan Borjan is making his first start for Ludogorets only four days after signing for the Bulgarian champions. First-choice goalkeeper Vladislav Stoyanov is suspended having been sent off in the play-off defeat of Steaua Bucharest when his replacement, defender Cosmin Moti, famously saved two penalties.

"When number two stopper Ivan Cvorovic was ruled out by a shoulder injury last Thursday, the club made an emergency move for free agent Borjan, who is Canada's number one. The keeper on the bench is 17-year-old Emil Gospodinov, who has never played a senior game, so if Borjan gets a red card maybe we will see Moti putting on the gloves again."

A centre-half saving penalties? Ludogorets' qualification was simply miraculous.

Over to BBC Sport's Sam Sheringham: "For those who missed it, Cosmin Moti was the outfield player who volunteered to go in goal after Ludogorets keeper Vladislav Stoyanov was sent off in the final minute of extra time in their Champions League qualifier against Romanian champions Steaua Bucharest.

"Despite previously having worn gloves only to stave off the cold, Moti dived to his right to save two of Steaua's spot-kicks and seal his team's passage to a group stage campaign which begins against Liverpool at Anfield on Tuesday.

"Moti, who had spent seven seasons playing for Steaua's arch rivals Dinamo Bucharest, leapt over the advertising hoardings to celebrate with fans, while Ludogorets owner Kiril Domuschiev announced that a stand at their rebuilt stadium would be named after the team's new idol.

"When I got back to the locker room after the game, I had about 60 text messages and 40 missed calls," Moti, 29, tells BBC Sport. "Everybody wanted to congratulate me. That was when I realised I had done something special."

You sure had Cosmin son...

More from John Lukic on 5 live Breakfast: "My broader fear about Arsenal is that they'll lapse into what they did last season. At the weekend they had the game in their hands, then they dropped points in the last minutes to Manchester City - that was symptomatic of what they did last season.

"They really need to improve on that, and in terms of the Champions League they must ensure they qualify from the group. Looking at the teams involved you'd think they would manage that, but tonight is a very important game."

Arsenal midfielder Aaron Ramsey:, external Hoping for a repeat of last year's result, can't wait for it tonight.

No wonder Aaron's looking forward to his return to Signal Iduna Park. It was the Wales international's goal that earned the Gunners a 1-0 win at the venue in the Champions League group stage last season. Can he repeat his feat?

Bristol City remain the only team in League One yet to lose a game and three wins in a row has seen the Robins move ahead of Peterborough at the top. Tonight's opponents Port Vale have lost five straight games in all competitions and so Steve Cotterill's side are expected to consolidate their position.

Second-placed Peterborough slipped from the summit after a goalless draw at home to Notts County at the weekend and Darren Ferguson's side will be hoping to bounce back with three points against a Gillingham team that have not won a game since last month.

Meanwhile, Leyton Orient manager Russell Slade, who guided the O's to the play-offs last season, has been told he has one game to save his job with the club languishing in 20th place. They travel to 14th-place Notts County, who are without a win in two games.

Nobody I follow has yet managed to get the Ludogorets starting XI into 140 characters....

Jenni in Newtownards: Anfield will be rocking tonight - it's been too long a wait without top-level European football for a team with such a rich European pedigree and history. An early goal will settle the nerves and could open up the floodgates against the minnows Ludogorets. I can see this being a 4-0 or 5-0 victory for the Reds tonight.

Andrew: Borussia Dortmund away isn't a fixture you want to be going into with an injury-depleted, young and inexperienced defence. Arsenal could be in for a hammering tonight. 3-0 Dortmund.

A five-year wait for Liverpool in the Champions League then - and time has not done their last XI too many favours.

Of the team who started a 2-1 home defeat to Fiorentina in 2009, only Steven Gerrard and Martin Skrtel are still at the club, with right-back Stephen Darby now at Bradford, Yossi Benayoun at Maccabi Haifa, Diego Cavalieri back in Brazil with Fluminense and Dirk Kuyt now a full-back for Fenerbahce.

Former Liverpool and Republic of Ireland midfielder Ray Houghton on 5 live Breakfast: "Liverpool's league form has been patchy, won two but lost two. But European nights are very special under the floodlights, and they have been out of this competition for quite a while. The focus tonight will be on getting the three points.

"I'm sure they will pay the opposition the respect they deserve - Ludogorets are in the group stages on merit. They will plan to sit back and try to frustrate Liverpool as much as possible, and they will see what Aston Villa achieved at Anfield at the weekend. They will try to replicate that, but I think Liverpool will have too much quality and I expect them to win."

"It's a balmy late-summer's evening in Liverpool and there are smiles on the faces of the home fans as they mill around outside the ground relishing the prospect of the club's first Champions League outing in five years. Filtering through the doors of The Park pub across the road from the Kop is an aroma of sweat and beer and the full range of club songs being belted out at full volume. At the Paisley Gateway, Neil Poole is selling copies of his new fanzine 'We are Liverpool', with the front page splash 'European Reunion'. 'We're coming back home,' he tells me. 'This competition has a special place in our hearts.'

Manav Mehta:, external Bellerin starts - seemed decent pre-season. A brave decision but one that Wenger shouldn't have been in a position to make.

Faseeh Warind:, external Arsenal are not getting past the last-16 if we don't top the group.

Footy Ographer:, external All of Brendan Rodgers' achievements last season could be forgotten in a hurry if he falters in the Champions League this season.
