I highlighted Felix in another thread but he is an absolute no brainer. He will take 50M I would imagine but I believe at Tottenham he would finally join a club that would allow him the ability actually showcase his game and plat in his proper position (I also believe he would flourish at Barca).
He joined a train wreck of a club in Chelsea and his ability compared to anyone else in that team was night and day. The touch, the ability with the ball, passing etc were all there. At just 24 he is still very young and with a player with world class potential like he has Tottenham can possibly have a star player. Ange is an attack minded coach who could really help Felix in my opinion.
Although never being worth 120M, what he showed at Benfica was world class potential and even at Atletico he showed glimpses of it, however he plays for the most robust defensive coach in the world who consistently played him out of position.
Spurs have the money (Barca don't) and this kid is looking for a way out. Tottenham need to be ambitious and target this level of talent for their rebuild. To put into perspective Woolwich dropped 60M on Haverts who is not as talented as Felix is.
You can say whatever you would like but on talent alone he walks into this Spurs starting 11 with his eyes closed IMO.
