Bayern Munich boss Julian Nagelsmann has already hinted at the possibility of an exit for Benjamin Pavard with Chelsea linked to the defender. Meanwhile, Joakim Maehle and Denzel Dumfries options are also said to be available for Thomas Tuchel.
On the US tour, the Blues were able to confirm the acquisitions of Raheem Sterling and Kalidou Koulibaly - two signings which signalled intent from the new American regime. However, multiple setbacks with the likes of Jules Kounde and Presnel Kimpembe means that Tuchel still only has those two new recruits through the door ahead of the final pre-season clash on Friday night against Udinese.
It was expected that new owner Todd Boehly would provide the Chelsea boss with a £200million plus war chest in his first summer transfer window. With over a month before the window closes, there is still time to sign new players, but with Everton fast approaching, the German was under no illusion that this summer of change may mean that his side would not be ready for the new campaign.
