Abou Diaby will undergo stringent medical tests with West Brom this weekend, Football Insider sources understand.

The midfielder is in talks to join the Midlands club about a pay-as-you-play deal just weeks after being released by Arsenal.

Diaby’s West Brom medical will impact on the type of contract he is likely to be offered following the series of injuries that wrecked his Arsenal career.

The 29-year-old made just 182 appearances for the Gunners in nine years and was restricted to a single match last season, against Southampton in  the third round of the Capital One Cup.

He had a few run-outs as an over age player for Arsenal Under-21s at the end of last season to give hope that he can still play at the highest level.

But Arsene Wenger decided not to offer the former France international a new contract when his £60,000-a-week deal ended last month, although the player has continued to train at Arsenal’s London Colney headquarters.

Despite Diaby’s injury woes and the unlikely prospect of him being able to play two matches in succession in the future, West Brom manager Tony Pulis believes the midfielder could still be an asset for his team next season.
