It's a nothing story anyway. The only way we wouldn't activate that clause is if he was a complete crock.
Two Reasons:
1. If we want to keep him we get another year on his contract with no negotiations.
2. If we want to sell him it adds to his value and avoids a Bosman situation.
Complete nothing story.
The risk is that we want to sell him but can't find a club willing to match his £100,000 per week wages so he ends up hanging around like a bad smell for another year (harsh I know)
