Emirates skipper could be leaving to the Nou Camp but can the Gunners replace him?
Arsenal captain Cesc Fabregas looks likely to be heading to Barcelona this summer but can manager Arsene Wenger afford to let him go.
The problems the Gunners have at the back are well documented but without striker Robin van Persie for the second part of the season, they would have struggled in attack as well.
Home blanks against Newcastle United, Sunderland and Blackburn highlight how predictable the Gunners have become in front of goal but with Fabregas operating behind Van Persie it makes Arsenal tick.
He is the one who has the vision and ability to open up defences with a mazy dribble or exquisite pass.
Samir Nasri, despite an excellent first half of the season, faded after picking up a hamstring injury against Huddersfield Town in the FA Cup.
He would need to rediscover his form to have any chance of filling the Spaniards shoes but he has never shown the range of passing that Fabregas possesses.
Gervinho has been added to the squad to give more spontaneity to the three-pronged attack and signs from pre-season are good.
But without Fabregas who will be sliding the balls through to the Ivorian or Theo Walcott?
Will Van Persie drop even deeper to help his side when they really need him playing off the last defender and getting into the box.
The video below shows how essential Fabregas is to Arsenal and despite another season disrupted by injuries he bagged 11 assists and three goals in 25 league games.
