Chelsea made the first big move of the transfer window when they announced the signing of Christian Pulisic last week.
The Blues paid Borussia Dortmund £58million for his services and the American international now spend the rest of the season back on loan with the German club.
The 20-year-old admitted how Chelsea's style of play was a factor in his decision to join.
“I’ve seen their style of play,” Pulisic said, per talkSPORT.
“I’ve always appreciated how they’ve played football, and it’s really nice how they play now, with their new coach. It fits me very well.
“It’s been a dream of mine [to play in the Premier League] and I am really excited for this move and I feel like it was just the right time for me.”
But why hasn't Pulisic linked up with Chelsea straight away?
A report has emerged from ESPN that claims Pulisic himself made the decision to join in the summer.
He had the opportunity to join right away but turned it down.
ESPN write: "Sources told ESPN FC that the decision to join Chelsea in the summer, rather than in January, was Pulisic's to give him the best chance of impressing Chelsea manager Maurizio Sarri during a full preseason rather than half of a regular season."
That's a fair enough reason.
Pulisic must have been aware that, as a new player, it would have been tough to break into the first XI having not had any time to impress his new boss.
Joining in the summer is a wise move as he would have a number of months to impress Sarri and adapt to life at the club.
Dortmund's sporting director, Michael Zorc, also spoke very highly of Pulisic while at the club's winter training camp in Marbella.
"He's a lad who comes with that typically American self-confidence," Zorc told ESPN. "Many of his characteristics will help him in England where everything is just little bit more intense than in the Bundesliga.
"He has the pace, he's got the dribbling, he wants to get ahead at all costs. I don't know a single reason why he wouldn't make it there."
