Pulisic, 21, enjoyed a successful debut campaign in England following his €64 million move from Borussia Dortmund in 2019.

The forward's performances after the Premier League restart helped Chelsea finish in the top four, and he also scored in their FA Cup final defeat to Arsenal.
After being handed the No. 10 jersey, there will be more comparisons between Pulisic and Hazard, but the American has said he wants to create his own history at the club.
"He's an unbelievable player," he told Sky Sports last season. "It's pretty obvious what he accomplished at this club, and I'm not trying to compare myself to that.
"What's important for me now is winning games and having an impact for my team. I'm really happy I can do that as of recent and my style is always going to continue to be that very attacking-minded and creative kind of player."
