Wycombe midfielder John Mousinho is to stay at Adams Park until 2010 after triggering a one-year extension clause in his contract.

The extra 12 months arises from the Amersham-born player making 10 first-team appearances this season.

The 22-year-old has impressed since joining the Chairboys from Brentford in the summer.

Winger Gavin Grant will trigger a similar clause if he makes one more appearance for the club.
