Chelsea are the envy of the Premier League right now after the confirmed signing of Borussia Dortmund winger Christian Pulisic on Wednesday.
Manchester United, Liverpool, Arsenal and Tottenham have all previously expressed interest in the 20-year-old, who has risen to stardom during his three years in Germany.
Dortmund, who signed Pulisic for free back in 2016, made £58m from the transfer and negotiated to keep him on loan until the end of the season.
One man who has been persistently linked with Pulisic over the past year is Liverpool manager Jurgen Klopp, who was asked about the move in a press conference.
Speaking ahead of Thursday's title clash against Manchester City, Klopp said it was good business for both clubs.
"Really good player for Chelsea," said the German, per Sky Sports. "A skilled boy. I've known him for a while, good signing, good deal as well for Dortmund."
Due to the fee Chelsea coughed up for Pulisic, there's been suggestions that they overpaid for a player who has largely played second fiddle to Jadon Sancho at Dortmund this season.
Questions have also been asked of whether the American is the finished product - although in his defence, he's still only 20.
But let's focus on the positives, because Pulisic is undoubtedly a very exciting young talent who has the potential to be world class one day.
Pace is one of his biggest strengths and now a clip has emerged of Pulisic going head-to-head with Napoli's Kalidou Koulibaly in a race down the wing earlier this season in the Champions League.
Koulibaly is widely regarded as one of the best and fastest centre-backs in the world, yet in the video below, Pulisic demonstrates his speed and strength to roar past him from the half-way line.
Impressive. Chelsea already have Eden Hazard, Pedro and Willian who can play out wide, but Pulisic is arguably quicker and more direct than all three of them.
Premier League defences, beware.
