Fabregas has long been linked with a return to Barcelona, but recently the midfielder has also been linked with a move to Real Madrid.
Wenger said: “We need Fabregas. Believe me. He is a special player. He is exceptional and we want to keep them all.
“We go for all the competitions because we have the players to cope. We have the quality and the numbers.
“We are in a position where we can say no for financial reasons. We don’t need finances.
“People reproach me, saying ‘Why do you not spend stupid money?’. Now they reproach me and say, ‘Why do you not sell the player’. That makes me think we have not worked too bad.”
