The good thing with the Werner loan is he won't clutter the squad if we don't want him at the end of the season.
Obviously Ange did want to see more of him, but we shouldn't end up in a position like we are in with Ndombele, Gil, Lo Celso and many more previously where we simply can't shift them.
The getting rid of him part is already dealt with. No 3-5 years of salary obligations. If it were allowed, having players on 1 year contracts with exponential optional extensions would justify paying much higher wages.
