There isn't a single position in the Chelsea first-team squad that doesn't require attention this summer. And with the transfer window officially open as of today, it's time for Thomas Tuchel and new Blues owner Todd Boehly to get to work on the rebuild that is required.
It will not be easy, as Tuchel himself has accepted. "The rebuild is big," said the German last month. "The two top clubs [Man City and Liverpool] improve their teams – and they already have teams that are very clear on which to build. A rebuild is necessary for us, and that makes it more challenging, of course.
"We have clear ideas for the profiles and characteristics of these players. But it's not like we put a name on the list, and then we get the player. We have to convince the player, speak to their clubs, and convince ourselves this is the player [we need]. So there is normally a lot of work, and it will be the same to be competitive next season while everyone else tries to close the gap to us."
