He does best when he is underdog. He won CL with Porto and Inter but failed with us and Madrid.
First season was always to write it off. Spurs can be very dangerous with him.
His priority is to fix defense. He is capable we all know of making a team to concede less than 30 goals in the league.
They have worst full backs pairing in the league. Rose and Aurier.
Not sure about their budget but if I am Jose I would go for Tagliafico. One of the best full backs defensively plus cheap. Not sure for RB? They need some strong and tall dude. Surely he can find someone?
And if he pull that Skriniar-Ndombele swap that is it. Son and Kane will always get you goals. Many options in midfield area as well. And they need CF backup.
