There is absolutely no denying he's been very good since the restart, but this is Willian in a nutshell, some good, lots of average and shit shot in there also.
He should in no way be offered another deal here, move him on, we can cope without him.
Last night Souness mentioned something that was a typical non watching Chelsea fan would say.. "He's there best player by far" no, no he isn't and it is easy to say that when not watching every game you nob head.
He's hasn't been as consistent as Mount and Kovacic and no where near the level of Pulisic. There is this weird notion from commentators that he is some sort of absolute elite footballer, he's decent, that's about it.
