Samir Nasri’s proposed move to West Ham United has hit a snag with the Premier League club concerned at how long it will take him to be fit enough to play.

Nasri underwent a medical at West Ham on Monday ahead of signing a proposed six-month contract with the possibility of an option for another 12 months. However West Ham are understood to now be revising what they are prepared to offer the 31-year-old who is currently serving an 18-month ban for an anti-doping violation after using a so-called drip treatment at a Los Angeles clinic.

The ban ends on December 31, meaning Nasri would be able to play after that day. He is already free to train with a club from now but West Ham are concerned that it may take him too long to get up to speed and may not want to commit to wages believed to be around £80,000-a-week.

Instead the likelihood is they will seek to make an alternative offer with, it seems, an incentive for Nasri based on appearances. Whether the former French international accepts that remains to be seen.

Nasri is nevertheless wanted by West Ham manager Manuel Pellegrini who, of course, worked with him when the pair were at Manchester City.
