Apart from Witsel and Mata has @The Esk mentioned any others we're in for?
Begovic was discussed a few weeks back.
Esk isn't all knowing, he's the first to admit it, but he never shares anything more than his personal opinion unless it's information that has been clarified by his sources (at least two). It's why he's reliable in that what he passes on at the time is the working information - obviously that can change.
