Dont think the buy back clause is so cut and try as media is saying, Lewy would not see it be a loss to a club. If this kind of singing can help you push to top 4, then you would not do it? Push for better place is risk worth it with a player who improves that positsion so much, even if there is SOME possibility that he leaves in 2 years time. Ultimatly you have also have some money moving around if the club needs to clear some books. Ofcourse there is danger of player not working out or a dressing room problem, but lets face it that can happen with any player as we have seen time to time. Bascially loan move where money is moving around and there might be change that the players stays.
Also I understand Mou tactics and the perspetion he has in this forum, but dont make him sound like complete fool sunday leage manager, who could not change tactics if right players are coming in.
Regarding Kane. I really hope Lo Celso could take more the place of nr10 role when he comes back, to give Kane more movement up top, not droping down all the time. He played really well after the reset and team seemed better with him on the pitch. All are talking about Kane drop off, but I think Alli drop has been more bigger and constant already from Poch time.
