Chelsea fans were given quite the surprise on Wednesday morning when they woke up to news about Christian Pulisic.
Although there had been speculation that the Borussia Dortmund man could be moving to the Premier League, confirmation of the transfer came without warning and delighted supporters across Twitter.
Pulisic is regarded as one of the finest young talents in English football and Chelsea look to have secured themselves a long-term asset in their attacking line-up.
The man himself was incredibly pleased with his move, remarking in an emotional statement: “In summer I move on to Chelsea and to a new competition, the English Premier League.
“It’s a privilege to have signed for such a legendary club and I look forward to working hard towards being a contributor to their team of world class players.
Pulisic signs for Chelsea
“I am looking forward to working with Maurizio Sarri and his technical team."
Chelsea fans will be keeping a close eye on Pulisic's progress over the next six months, with the American winger regularly competing with Jadon Sancho for a spot in the starting XI.
And although the Pulisic move is a look to the future, he will need to justify the €64 million transfer fee and his arrival in general given players like Callum Hudson-Odoi fighting for a call-up.
Pulisic's performance against England
However, the Blues have clearly been tracking Pulisic for some time now and Maurizio Sarri was only briefly consulted after all the negotiations have taken place.
So it's hard to know exactly when it all clicked for Chelsea, but one supporter has tried to identify the moment Pulisic truly impressed the Blues.
According to him, that was his performance against England back in November, which ended in a 3-0 defeat for the United States.
And while most supporters were focused on Wayne Rooney's swan song for the Three Lions, many might have missed Pulisic's promising showing from the game.

It's not difficult to see the potential that Chelsea clearly identified.
It wasn't necessarily the flashiest of performances but he was delivering the type of invention and dynamism that the American team so desperately lacked at Wembley Stadium.
The Guardian called him the 'USA's best player' and noticed his 'excellent dribbling' yet did concede that his final ball was lacking on the night.
Nevertheless, such an exciting display when game-time has proven hard to come by at Dortmund could easily have persuaded Chelsea to put their money where their mouth is.
The jury is still out on how Pulisic could perform in the Premier League, but he certainly has the talent to become a real asset for Chelsea.
If he can perform like he did during his last visit to London, then plenty of defences will simply cave in.
