Arsenal manager Arsene Wenger has admitted midfielders Cesc Fabregas and Samir Nasri are both close to finalising moves away from the club.
Fabregas is on the verge of signing for European champions Barcelona for a fee believed to be about £35m.
Nasri is set to move to Manchester City with the clubs close to agreeing a fee between £22m and £24m.
“We hope it will be sorted out very quickly one way or the other,” Wenger said of Fabregas.
“The Nasri situation is stable. Again it is very difficult to speak about possible transfers but we are in a situation where we have to make decisions one way or the other. Ideally you want it to be sorted out before the season starts.”
A senior Arsenal source has told BBC Sport the funds generated by Fabregas’s sale will be reinvested in new players.
The Gunners have been linked with Scott Dann, Phil Jagielka and Gary Cahill.
Wenger looks intent on strengthening his defence and reports have suggested centre-backs Dann of Birmingham, Everton’s Jagielka and Cahill of Bolton could be targets.
Fabregas, 24, would be unable to feature for Barcelona in the Champions League if he plays a part in Arsenal’s match with Udinese on Tuesday. It now seems Wenger expects the deal to go through before the Gunners’ Premier League opener this weekend.
