Payback time for Arsenal and Fiorentina

Arsenal - Porto FC at Emirates Stadium

European Champions League on Twitter

First leg result: Porto FC 2 - 1 Arsenal

Teams review:

Arsenal: Along with William Gallas and striker Robin Van Persie, Arsenal will also miss captain Cesc Fabregas. The club's top scorer (17 goals, 15 assists) has been ruled out after a hamstring injury during a match with Burnley last weekend.

Porto FC: More good news than bad for the Dragons. As midfielder Fernando is ruled out for injury, Raul Meireles, Nuno, Fucile, Rolando and Brazilian star striker Hulk are back in the team.

Stats:

In their last 24 European encounters, Porto have qualified to the next round after winning the first leg. But Porto has a pretty bad record in London. Their last experience this season was a 1-0 losss to Chelsea in the group stage (1-0). Last year, Porto left the English capital with their worst result in the competition: losing 4-0 against.......Arsenal.

French players to watch: Samir Nasri, Gael Clichy, Abou Diaby, Bacary Sagna

Last results:

Arsenal 3-1 Burnley
FC Porto 2-2 Olhanense
