Joao Felix has joined Milan on loan from Chelsea, his fourth club in three seasons.
What happened to Joao Felix?
He signed for Chelsea on loan, then permanently, but has done very little, sparking concerns about his career.
Atletico Madrid paid Benfica €126m for Joao Felix in 2019, a move that may have been too soon.
Why the big transfer fees?
Joao Felix's transfer fees total €178million, with 37 league goals in five and a half seasons since leaving Benfica.
He was compared to Johan Cruyff when he broke through in Portugal, but now looks like a player who can't escape the waiting room of his own career.
What's next for Joao Felix?
Joao Felix is still only 24, but his career is at a crossroads, with many questioning his talent and dedication.
He has been used mainly as a deluxe bargaining chip, rather than a key player, at his previous clubs.
The selection of Jorge Mendes as his agent has reduced sympathy for him in some circles.
Joao Felix's natural brio has repeatedly slammed into the brick wall of Diego Simeone's personality at Atletico.
He may have been better off joining Manchester City, a team whose playing style aligns more closely with his game.
But for now, Joao Felix remains a footballer who can't get a game anywhere, despite being the fourth most expensive player of all time.
