Well yes, but:
1/ His knee if it as bad as rumoured/speculated may not allow him to
2/ The club and/or could opt to pay him out
Having said that the lack of Crouch this season is one of the key reasons why we have won less games this season.
He has the talent and ability to play on next year that is for sure. He might just be short one serviceable knee. Personally I would like it they can get his knee good enough for him to play a whole season again. But, they may not be able to.
