Cesc Fabregas & Samir Nasri near moves to Barcelona & Man City

Fabregas and Nasri scored a total of 24 goals in all competitions last season

Arsenal 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.

BBC Sport also understands that Nasri is set to move to Manchester City with the clubs close to agreeing a fee between £22m and £24m.

According to a senior Arsenal source, all 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.

Gunners boss Arsene 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, motivating both clubs to complete a deal before that game.

It is believed that, if he is sold, the Spaniard will be due £4m in compensation - £1m for each year of his contract he did not complete - but may be prepared to forego that payment in order to facilitate a deal.The BBC understands a fee of £30m, plus over £5m of additional performance-related payments, is close to being reached for Fabregas.

Negotiations have been conducted by Barcelona's vice-president Josep Maria Bartomeu and is believed to be a final take-it-or-leave-it offer, leaving Arsenal having to sell one of the major assets or keep a player who has his heart set on a move.

The transfer fee is significantly less than the £40m that Arsenal had been holding out for and suggests that the Gunners felt they had no choice but to sell a player who wanted to leave.

Fabregas, who has 58 caps for Spain, joined Arsenal from the Catalan giants in 2003 and, since making his name in north London, has been persistently linked with a return to his boyhood club.

If the Fabregas deal goes through as expected, he will become Barcelona's second major signing of the summer following their £23m purchase of Chilean forward Alexis Sanchez.
