While I am not opposing what Mourinho may have in mind for his transfer, this rumor sounds strange. Draxler is not that good and injury prone. With the money being talked about here, we can get Sane or even a more proper player in James Rodriguez.
If talking about compatible to Mourinho's tactic, then it's even stranger. Draxler can carry the ball well, but took too long before releasing the ball. Not a very much team player. He has the tool: passing, vision, but application is no where near. Proper use for poor man Reus term.
I am not the usual play our youth instead of buying guy, but if there is a chance Mourinho can motivate Januzaj to perform like his Moyes season, that kind of Januzaj arguably would not be too far from the current Draxler.
