Christian Pulisic has admitted the fee Chelsea paid to sign him from Borussia Dortmund has him excited about moving to Stamford Bridge, and says it shows how much the Premier League giants want him at the club.
Last week, the 20-year-old midfielder completed a €64 million (£57.6m, $73.1m) deal to join the Blues in what was a record transaction for an American player.
"For them to do this and to want me this much I think yeah they must like me, at least a little bit," Pulisic said in an exclusive interview with ESPN FC's Raphael Honigstein.
Per the terms of the agreement, Pulisic won't join Chelsea until the summer though he insisted his mind is still set on playing with Dortmund, and not his new team.
"I've been here and playing with Dortmund the whole time and I've been focused here, but I'll be really excited once the time comes," said Pulisic.
"I'm really happy with my decision at the moment. I don't have any regrets. I'm really excited, but yeah. The best thing is I get to finish out a strong season here. After that, I can move on to this next step."
Once he moves to Stamford Bridge, Pulisic, who can play as an attacking midfielder or a wide forward, is unsure of what role he'll occupy in Sarri's team.
"I think they definitely see me in one of the wider areas, but I think they also know that I can play kind anywhere across the attack. So I'm ready for wherever I need to be filled in really."
Last week, Pulisic said Chelsea's brand of football under Sarri was a key factor in his decision to join Chelsea.
He explained why he believes his style and Sarri's are such a good fit.
"Yeah, I think just from watching the games that I have been able to catch this year I just see a system in how their wingers play," he said. "It's just a really good attacking, flowing system, and it's just football that I like to watch.
"I think they like to play out of the back, they're not afraid to play anywhere on the field and they're also very free once they get up the field. So it's just something that I like to see."
Pulisic, who has lost his starting place in Dortmund boss Lucien Favre's team over the last six months, acknowledged he won't be handed a place in the team despite the price Chelsea paid for him.
"Yeah, I mean it's going to be the first time obviously for me [in] clubs like this. I'd imagine when you first go in you have to go in and you earn the respect of the guys," he said. "I'm sure they're all great guys off the field, just like this team is and you got to go in and on the field you have to earn your spot.
"Every training, every game, any time I get the opportunity, just like here I have to take it and I have to prove to them that I'm worthy of being on the field and playing with that team. Once I get there then I'll just be fighting every single day and I'll be ready for it."
