Chelsea have already made their official first signing of the Mauricio Pochettino era but by bringing in 16-year-old Kendry Paez, they have brought in a player that agreed to join them whilst Graham Potter was the manager. It's not to worry for the incumbent manager, though, more are expected to follow.
Christopher Nkunku has a pre-agreement to join the club and is now just an announcement away from being confirmed. His future is one of the worst-kept secrets in the game. Despite wholesale changes across the board, he also isn't expected to be the last.
Pochettino is seeking improvements in three key areas this summer and has already been dealt a major blow in his bid to add depth to one of those positions. With a new goalkeeper - or maybe two - needed as well as a striker, there are still some big deals to be done.
