Well he's being consistent at least, he was at Shakhtar and then went to Anzhi even though Spurs and Chelsea were interested in him then. You can't really say the same for Thiago though.
It's more the comparison of a player joining a club for the money rather than the opportunity of first team football. Munich didn't need Thiago like Chelsea don't need Willian. It's bizarre, surely must mean Chelsea will let us have Mata... or is that wishful thinking?
