Nasri, Diaby, Sagna: Who Can Be The Linchpin For Arsenal Against Barcelona?

Two of the most exciting teams in World Football will go head-to-head tonight in the first leg of the Champions League quarterfinal when Arsenal takes on Barcelona.

Barcelona, the kings of the crown, against Arsene Wenger's youthful Gunners.

Most are expecting a routine win for the Spanish giants, but others feel Arsenal are capable of conquering the current Champions.

There is a slight concern for the Gunners, however. Captain and midfield maestro Cesc Fabregas is struggling for fitness after picking up a knee complaint against Birmingham over the weekend.

It will be a devastating blow if the Spaniard is unable to participate against his former employers, as not only will it leave a dent in the Arsenal attack but it will also mean the Gunners will lack a fearless leader on the field.

Fabregas will be sorely missed, especially as Barcelona boast an incredibly strong outfit with the likes of Lionel Messi and Zlatan Ibrahimovic dominating their attack. But even with the absence of Cesc Fabregas, Arsenal still has a formidable lineup.

So who can provide the act of brilliance needed to dethrone the Spanish kings?

Will Samir Nasri repeat his brilliance against Porto?

Can Andrei Arshavin shrug off his current form shackles and perform to his peak?

Or are we going to see little Bacary Sagna as the hero for the Gunners?
