Arsenal are demanding £8.8million to sell Laurent Koscielny in the current transfer window.

The 33-year-old defender has made it clear he wants to quit the club he joined in 2010 and return to France, with Bordeaux, Rennes and Lyon all interested in pursuing a deal.

However, as Standard Sport revealed yesterday , as yet no club has tabled a formal bid for Koscielny, who must now wait to see if any of the Ligue 1 sides meet the Gunners’ valuation of €10million.

Koscielny has a year left on his current contract—worth an initial £90,000-a-week—and Arsenal rejected a request from the centre-back to release him from those final 12 months.

Bordeaux have hinted they will offer Koscielny a three-year deal, a length of contract the Gunners are unwilling to match. They have suggested in talks to this point that a year extension based on how his longstanding Achilles problem progresses is the most likely offer they will make.

That prompted Koscielny to push to leave, a stance which reached an impasse on Thursday when he refused to board the flight to America for the club’s pre-season tour.

It is possible Koscielny could seek to explore buying himself out of Arsenal contract in order to become a free agent.

The prospect of keeping a player against his will may also prove unpalatable for head coach Unai Emery, who was said to be furious with Koscielny over his attitude.

Koscielny believes he deserves to have his request granted in recognition of nine years’ service to Arsenal but, in turn, the club were shocked that their captain would attempt to force his way out in the manner he has.

Koscielny will continue to train at London Colney with the fringe and youth-team players left behind from Emery’s 29-man squad that travelled to the US. Mohamed Elneny and Krystian Bielik were notable absentees, though both were involved in international competition this summer.

Meanwhile, the club this morning confirmed 21-year-old midfielder Ben Sheaf has joined Doncaster on a season-long loan.
