Cesc Fábregas has admitted he feels frustrated at Arsenal, but insists he will not press for a summer transfer to Barcelona.

On Tuesday his Arsenal team-mate Bacary Sagna claimed Fábregas had decided to seek a return to the Catalan club where he came through the youth system before moving to London in 2003. However, Fábregas has insisted that he will not agitate for a transfer.

Fábregas said: "Barcelona are the best team in the world and going there guarantees titles. But I owe myself to Arsenal.

"Any player who says he is not frustrated at not winning titles is lying. I am ambitious. [But] I have not spoken to the manager. He is the boss, he takes decisions and I don't know if they want to sell me or not.

"I have values and after all that I have done in eight years here I am not going to say a word that would ruin everything. I have always acted with discretion.

"Everyone sees things in a different way but in these [sorts of] decisions, not everything depends on the player. If I said anything else it would be a lie, it would give rise to speculation that is not true.

"I am very happy at Arsenal. I am not going to talk about any team – but I can't say no to anyone because you never know what could happen in the future."

Barça have tried and failed to sign their former player in each of the last two summer transfer windows.

According to reports in Spain, the European champions would have to pay around €40m (£35.2m) to secure Fábregas, who is seen as a natural replacement for their playmaker Xavi, who turned 31 in January.

While Fábregas admitted he was frustrated at Arsenal's repeated failure to land a trophy, he said he believed the club had the resources to end their barren run. "A player who is not frustrated at not winning titles is either lying to himself or lacks ambition," he said.

"There is a good team and a good manager and one of the most faithful fan bases in Europe. With those I believe we can make progress and one day win an important trophy."
