Chalobah Recalled to chelsea

[Canterbury Palace]

But Chelsea wouldn't want to sell in this window if they're prepared to eat humble pie and call Trevoh back despite having told him he wasn't wanted last summer.

This is a good point. Though I've never really understood how those clauses work. Surely any club can match the bid that any club puts in anyway? Or is it just that we have to inform them of the bid and see if they want to match it?
