Mark, Belfast: As great as our first three performances have been I can't see Northern Ireland winning tonight. I fancied us against Hungary and Greece but without our instrumental skipper (Steve Davis) tonight could be about snatching a point. If Lafferty brings his 'A' game then we have a chance but a draw would be an unbelievable result! Can't help thinking that our rollercoaster is about give us our first big twist!

Everton left-back Leighton Baines withdraws from the England squad to face Slovenia and Scotland through injury.

His absence means that Arsenal defender Kieran Gibbs is the only recognised left back in the squad. Three Lions boss Roy Hodgson will not call up a replacement.

"Baines picked up an injury in training on Friday morning and will return to his club for treatment," says the Football Association., external

Wayne Rooney will celebrate his 100th England cap tomorrow. You might have heard. But how decisive has the skipper's contribution been in terms of goals? Let our colourful graphic dazzle you.

Skipper Alastair Cook tells the BBC that he believes next year's World Cup represents England's best opportunity to win it.

"Since 1992 (when England were beaten by Pakistan in the final), I don't think we've done ourselves any justice in the World Cup," Cook said.

"The planning from the ECB has made sure we have the group fresh and ready to go. We have an extended period of one day cricket as players.

"I, for one, am really excited about playing one day cricket where we haven't got test cricket in the forefront."

John McEnerney:, external Two ex-Celtic managers in the technical areas, both sides have improved under Martin O'Neill and Gordon Strachan. Fast and frenetic - 0-1 to The Republic!

Do you agree with John's prediction? And which of the ex-Celtic bosses - O'Neill and Strachan - will get the biggest roar from any Scottish/Irish Bhoys fans at the game?

Wales forwards coach Robin McBryde warns Richard Hibbard he is "playing with fire" if he gets injured for Gloucester.

Hibbard will be on the bench against Harlequins, despite being unavailable for Wales' Test with Fiji. McBryde says the hooker is risking his place in the team to face New Zealand on 22 November.

"If he does take the field he jeopardises his inclusion next week from a fitness point of view," he says.

Excitement building for tonight's Scotland v Republic of Ireland clash yet? It should be. And if it isn't then here's a bit of early team news from Glasgow.

Scotland are without midfielder James McArthur, who has returned to his club Crystal Palace with a calf injury.

McArthur's former Hamilton and Wigan team-mate James McCarthy (hamstring) is missing for Ireland, who are also without Stoke City midfielder Glenn Whelan and Palace striker Kevin Doyle.

League Two side AFC Wimbledon submit a planning application to Merton Council for a new stadium at Plough Lane.

They propose building a 11,000-capacity stadium, which could be expanded to 20,000 at a later date, on the site of Wimbledon Greyhound Stadium.

The old Wimbledon FC, FA Cup winners in 1988, left Plough Lane in 1991 and eventually relocated to Milton Keynes, before becoming MK Dons.

A residential development now stands on the site of their former home, while AFC Wimbledon play at Kingston-upon-Thames.

Earlier, we told you about Stoke City striker Peter Crouch's cheeky claim that he realised that "there were problems with decision making at Fifa" when he wasn't named on the Ballon d'Or shortlist.

Now his club have responded with this...

"We were shocked too Peter... So, we have got you a special 'Crouch-on d'Or' waiting for you in the office!" the Premier League club tweets., external

Well, that didn't take long.

Novak Djokovic, looking so fresh it's as if he's spent the last hour reclining on his favourite armchair while reading a novel, has just completed a 6-2 6-2 victory over Tomas Berdych at the ATP World Tour Finals in London.

It sends Djokovic through to the semi-finals - where he'll face Japan's Kei Nishikori - and ensures the Serbian master will end the season as world number one.

Despite his defeat, Berdych can still go through. All depends on the outcome of tonight's game between Marin Cilic and Stan Wawrinka. That starts at 20:00 GMT.

England batsman Nick Compton departs Somerset by mutual agreement with immediate effect.

"I have loved playing for Somerset, but I have decided to re-locate more permanently to my base in south-west London," says Compton, who has yet to reveal which county he will join.

"I have always set myself the highest of professional standards, and I don't want to compromise myself or the club, going forward."‎

Andrew, Belfast: Northern Ireland are on the cusp of achieving something great in this qualifying campaign. I know it's not an easy prospect, but any sort of positive result tonight would put us in a very strong position for qualification. It would leave Michael O'Neill's mean on 10 or 12 points after just four games, and all that after playing Hungary, Greece and Romania away from home. This is our time, I can feel it!

If you are on your dinner at work and eating some sandwiches, don't read on.

In what could be the most gruesome entry of today's Sportsday, we bring you news of Victor Dubuisson's troubles during the second round of today's Turkish Open.

The Frenchman suffers from allergies and needed on-course assistance to treat a persistent nose bleed. Blood dripped onto his golf shirt and Dubuisson had to jam some tissue up his nose in order to stem the flow.

"It's not good and I didn't feel well at all," the 24-year-old, who was two-over for the tournament through 13 holes when a storm halted play. That score leaves him 15 strokes adrift of pacesetter Ian Poulter.

The Football League has also announced that all three divisions will conclude at different times across the final weekend (2/3 May 2015), the idea being to give each competition its own share of the spotlight.

The final weekend will begin with the climax of the Championship season at 12.15pm on Saturday, followed by the end of the League 2 season at 3pm. The last day of the League 1 campaign will take place the following day, with matches kicking off at 12.15pm.

Get ready for plenty of vanishing spray fun from the new year onwards.

The Football League has announced it is to use the spray from January 1 in the Championship and Leagues One and Two.

The spray is already used by referees in the Premier League and, much to the delight of photographers, has already resulted in some comical moments.

New Burton Albion boss Jimmy Floyd Hasselbaink is urgently seeking goalkeeping cover after Dean Lyness suffered a suspected broken leg.

The 23-year-old was hurt in training on Thursday, former Leeds, Chelsea and Middlesbrough striker Hasselbaink's first day in charge of the Brewers.

Burton visit League Two leaders Wycombe on Monday.

If I was a top tennis player, I think I'd be thoroughly cheesed off with Novak Djokovic. The guy is just too good.

He has just blitzed through the first set against Tomas Berdych at the ATP World Tour Finals in London, taking it 6-2.

Bearing in mind he has already blown away Marin Cilic 6-1 6-1 and and Stan Wawrinka 6-3 6-0, it shows just what a class act he is.

One more set to win and he's in the semi-finals, with three wins from three group games.

Confirmation of the news we broke earlier - Caterham will compete in the Abu Dhabi Grand Prix next weekend.

The team is £500,000 short of the £2.35m they are trying to raise via a crowdfunding project to allow them to compete.

But sponsors have come on board to allow the administrators to get the cash-strapped team to the grid for the final F1 race of the season.

Joint administrator Finbarr O'Connell said: "In only a week the fans have made the impossible, possible. There aren't enough words to say how grateful we are."

Scotland v Republic of Ireland at a packed Celtic Park. Should be an absolute belter.

Scotland are third in the group, Ireland a place higher, so the result could prove crucial in terms of who will qualify for Euro 2016.

BBC pundit and proud Scot Pat Nevin reckons the wide men hold the key and, though he could be accused of being a tad biased, believes the hosts will edge it.

"I thought it would be a draw before, but having looked at their weaknesses and the players they've got missing, I think we're going to sneak it, 2-1 maybe," said Nevin.

We shall see. The game kicks of at 19.45 with live text on the BBC Sport website.

All day we have been chatting about Wayne Rooney, now it is time to switch focus to tonight's matches featuring the rest of the Home Nations.

So how crucial is tonight's clash at Celtic Park in terms of the overall qualification picture? And who do you think will win? Meanwhile, can table-topping Northern Ireland reach their first major finals since the 1986 World Cup?
