The Spain World Cup winner returns to the team he left as a teenager for the first time in a competitive club fixture following another summer of transfer speculation over a £30million move.

However, Fabregas, 23, insists after battling back to fitness from a hamstring injury to play tomorrow, delivering a performance for the Gunners is his only focus.

"I am not here to shut up comments or to beat anyone specifically or whatever. I am just here to win for Arsenal Football Club," Fabregas said when fronting the media at the Nou Camp this evening.

"Sometimes I don't understand these reactions or comments about people saying I want this or I feel this. I want to win for Arsenal and that's it. That's easy for me.

"I don't put anything extra in my head because I play against Barcelona in the Nou Camp.

"It is a special game for everyone because it is a special stadium and we play against a good team and that's it. Its one more game that we want to win.

"We want to do well for the club and we want to get through to the next stage of the Champions League.

"There is nothing more to it than that - we just want to go through and get to the quarter-final."

Fabregas, though, revealed the prospect of having to miss another chance to face his old club was a difficult period.

"Over the last few weeks I have suffered a bit because I was a bit upset because I did not know whether I was going to make it, but I have great feelings now," the midfielder said.

"Sometimes you cannot take a big gamble to come back quicker. I have a lot of experience in that so I prefer to be safe."

Fabregas insists, despite what the critics claim in the wake of their shock Carling Cup final defeat to Birmingham, Arsenal do indeed have the spirit needed to deliver some long-overdue silverware this season.

"We have played so many games where we've shown we have character, we have potential and that we are the present," he said.

"We want to win things for the club and tomorrow is obviously a fantastic exam for all of us as a team and individually.

"We want to show how good we are and it's a fantastic opportunity for the team to have a great game."

Fabregas missed last season's Champions League quarter-final encounter at the Nou Camp after suffering a broken leg in the first tie in London.

The Gunners skipper knows full well his side, boosted by the possible return of leading scorer Robin van Persie, cannot allow Lionel Messi to run riot again, the Argentinian having netted all four goals in a masterclass last April.

"We know that you cannot give space to Messi because he scored four goals and was outstanding," Fabregas said.

"For the rest, we showed what we have to do in the first leg a couple of weeks ago and we played some good football.

"We have to play our game as well - we cannot always be focused on thinking what are they going to do or just defending.

"We are Arsenal and we have to make ourselves respected as well and we have to play our game as well as we can."

Fabregas added: "We have got to be ready for everything. We know Barcelona keeps possession on the ball, something like 70% of the game and we are not used to that.

"We have to be intelligent and mature enough to solve the problems they may cause, then also be ourselves and play our game."
