I don’t see anything concrete, just the over excited dot connecting of clickbait rumor mongers. It does make sense for Chelsea to move some attackers in order to rebuild the defense once the sale goes through (mooted to be this week
per the Guardian).
Pulisic has 2 years left on his deal at a reported £150k/week. I think he’s hard pressed to top that wage figure given his recent performances and injuries. But if he is willing to drop down a bit, he could have a wealth of options. Chelsea still has about £16m in amortized transfer fee on the book for Pulisic, so my guess is they’d be looking to get in the £40m range for our boy.
