Lionel Messi, Luis Suarez and Neymar start in attack for Barcelona, with Xavi on the substitutes' bench.

Sam Roath: Messi, Suarez, Neymar. By far the best attacking trio in the world.

Harry Dickens: At international level, Messi and Aguero is an almost unstoppable pairing.

Liam Hammond: I quite like the look of Jay Emmanuel-Thomas and Matt Smith at Bristol City.

As if there isn't enough to look forward to this evening...

Luis Suarez, the reigning player of the year in English football, will make his first appearance in England since his move from Liverpool in the summer for £75m.

He was made to wait in Spain, serving a four-month ban from football-related activity for biting Italy defender Giorgio Chiellini during the World Cup, and hasn't really set La Liga on fire yet.

But you wouldn't bet against the Uruguayan making a big impact one way or another this evening. You can read about his first eight months in Spain here.

BBC Sport's Jonathan Jurejko in Manchester: "The gusty wind might be biting cold in the city centre, but the atmosphere is starting to warm ahead of Manchester City's Champions League tie against Barcelona.

"A healthy throng of Catalans have arrived, most wrapped in thick overcoats, thermal hats and replica scarves, as they gather for a pint outside of one of Manchester's most historic pubs.

"Most fans I spoke to reckon their team will bounce back from a shock home defeat by Malaga and take an advantage back to the Camp Nou."

Arasa: RVP and Adebayor - led Arsenal well only for Van Persie to get injured. It dented AFC's hopes of winning the league.

RedViperofDorne: Diego Costa and Branislav Ivanovic are a pretty good strike partnership.

Duncan Radband: Has to be John Barnes and Luther Blissett.

As if tonight's Champions League action wasn't enough to keep you entertained, there's also a packed programme of Football League fixtures.

The top two in the Championship are both in action, as Derby take on Charlton, with second-placed Middlesbrough hoping to make up ground with a win over Bolton.

The bottom three clubs are also in action, with Blackpool visiting Brentford, Wigan taking on Cardiff and Millwall up against Sheffield Wednesday.

Plenty of eyes will be on events at the DW Stadium in particular for a match that pits Wigan manager Malky Mackay against his former club. The Cardiff board are set to boycott the match in protest at Wigan's ownership and management.

You can follow all the action with our dedicated Football League live text here.

Not quite the red carpet but Manchester City are doing their best to impress with this welcome for Barcelona's footballing royalty.

Barcelona's progress from the group stages, on the other hand, was as smooth as silk.

The Catalans lost just one match - to Paris St-Germain - and qualified top of Group E.

Forget the past though, this is all about now.

For many Manchester City fans, just their presence in the last-16 in the Champions League this season is a bonus.

They looked to be heading out of the competition after failing to win any of their first four games.

However, a 3-2 home win over German champions Bayern, which included a Sergio Aguero hat-trick, kept alive their hopes of making the last 16 - and they took full advantage with a stunning 2-0 win in Rome.

Breathtaking stuff.

Steven Jerjian: Aguero is key man because if he's not on form then City will struggle badly. Barca can afford for Messi to be off the boil.

We're asking you for your favourite strike partnerships in world football. Here's a few early shouts...

Gasumba innocent: Dwight Yorke and Andy Cole were the best striking partnership for me.

Chris: Robbie Fowler and Stan Collymore had a devastating partnership for Liverpool, loved them together.

Martin Lunt: Roy Race and Blackie Gray had everything, pace, goals, teamwork, everything.

So who do you think is going to be the key player this evening? You can have your say by using the vote facility on this page.

Manchester City are not scared of Barcelona, says captain Vincent Kompany despite losing 4-1 on aggregate to them at the same stage last season.

"We want to play against them. You don't go in at this level fearing strikers," said the Belgium defender. "They're a special team with special players, but there's nothing new to worry us, it's a case of having the whole team at a very high level."

Bold Vincent.

There will be no shortage of attacking talent on show tonight. Lionel Messi, Luis Suarez and Neymar for Barcelona, while City could pair Wilfried Bony with Sergio Aguero.

That got me thinking about some striking partnerships from the past, so I want to know who your favourite strike pairings have been in world football.

I would go for Ian Ormondroyd and Ian Olney - but then I'm a sucker for a long ball. Tweet your suggestions and reasons to #bbcfootball, , externaltext 81111 (UK users only) or post on BBC Sport Facebook.

Barca fans have been arriving at the Etihad Stadium throughout the day. This happy bunch look fairly well prepared for the Manchester weather.

Sense of deja-vu anyone?

Manchester City met Barcelona at this stage of the competition last time round and, for supporters of the blue half of Manchester, it didn't end well.

Manuel Pellegrini's men lost both legs to go down 4-1 on aggregate as the gulf between the two clubs appeared to be pretty big.

Has that gap narrowed at all? We will find out soon.
