Tbh, if that's what he needs to kick-start his career I won't bedgrudge him the transfer and I'd be happy to see him play well again. He doesn't seem capable of doing it here though, it's been 4 years of nothing. It's been over a year since he recovered from his injury and he doesn't seem to have the same ability and drive. And he won't be played until he re-discovers either of them here. Which is fair enough.
He has showed glimpses in his best form and fitness period here which is good enough as he has that higher ceiling. You Would not expect a player to come back to form for atleast 6 months after a double leg break like that, and he again got injured when he came back which was again a contact injury. The conditions are too harsh straight after such injuries.
Yes in terms of fitness and work ethic he has to do more and mentally toughen up, but when he'll be fit he'll be what we need him from him. Just look at Phil jones's career, Plagued by injuries after injuries which was not even contact injuries like in the case of luke shaw, was terrible under moyes and LVG, had injuries under jose too and most of cafe was of the idea of him being sold, now when jones has matured he's the first choice prefrence of mourinho and playing wonderfully well. With luke shaw we should accept pretty much the same, We should stick around him.
The cafe expects him to be sold very quickly but does not go on about the fact of who must replace him who has that higher ceiling about him, Rose for me is not the one at all, He's a ok player who's already playing on his peak but still not considered to be world class enough and the other only remains to be alex sandro who'll cost a fortune but we have not watched him that much yet.
Luke shaw does not need a move to come back to the best, He needs patience and game time and dicipline and work ethic in his life which will come with stability and hardwork and he's vowed to respond. He did not have a preseason like other players and he'll take some time to get back to the level he needs to be.
