Arsenal vs Barcelona: When will Barcelona score in tonight's Champions League tie?

VOTE: When do you think the Spanish champions will get on the scoresheet at the Emirates - if they do at all?

Few are giving Arsenal a chance of stopping Barcelona in their Champions League Round of 16 tie.

The main reason for that is the form of MSN - Lionel Messi, Luis Suarez and Neymar - the trio that have been ripping defences apart at will this season.

Between them they've scored 91 goals in all competitions and have six assists and 10 goals from the six Champions League games they've already played this season. Suarez alone has scored in each of his last seven games and has 15 goals in his last nine matches.

So for many it's more of a case of when, not if, Barcelona will score an away goal at the Emirates this evening.

However, should it be? One thing in Arsenal's favour is Petr Cech's record against Barcelona's front three. In six games Messi has failed to score, Suarez has two but over five games and Neymar has never put one past the Arsenal goalkeeper (although he's never played him).

But what do you think? Take part in our poll below...

Tonight's match kicks off at 7.45pm.
