Fabregas has faced months of speculation after Barcelona's leading presidential candidate Sandro Rosell vowed to take the midfielder back to his native city.
Staying put: Cesc Fabregas in action against Barcelona recently, but Arsene Wenger insists his captain won't be joining the Spanish club this summer
'Do you want to see the length of his contract?' said Wenger, asked about his captain leaving the Emirates this summer. 'Players at the end of contracts can sign where they want but, with the players who are under contract, we decide on their future.'
Fabregas's deal runs until 2014, and Wenger added: 'We are not under any financial need, we are well managed and that gives you one luxury in that you can decide about the future of your players.
'This team is on the way up and we don't work for four or five years with young players, stand up for them and let them come through and then, when they are ready to perform, sell them. That would be irresponsible.
'Some people are specialists at making players unhappy. I cannot stop them talking in Spain. But all of the players who have left here wanted to return.'
Fabregas is out after breaking a leg in the first leg of the Champions League quarter-final with Barcelona but hopes to be fit for the World Cup.
