Chelsea have completed the signing of England Under-21s winger Noni Madueke from PSV Eindhoven in a move worth about £30.7m.
The 20-year-old joins on a seven-and-a-half-year contract, with the option to extend for a further year.
He is their sixth January signing and Transfermarkt puts their spending this month at 178.50m euros (£156m).
During the January transfer window, the Blues also acquired David Datro Fofana, Andrey Santos, Benoit Badiashile, as well as Joao Felix on loan.
It follows a summer in which they broke Premier League spending records, spending a total of £270 million, second only to Real Madrid’s £292 million summer spending in 2019.
“I’m really pleased to sign with one of the best clubs in the world,” Madueke told the club’s website.
“To return to England and play in the Premier League is a dream for me and my family and I can’t wait to get started.
“I am excited for what the future holds, the owner’s vision for the future and to be at a club like this and winning at the highest level.”
Before leaving England to relocate to the Netherlands and sign with PSV in 2018, Madueke went through the youth systems at Crystal Palace and Tottenham.
He has four England Under-21 caps and scored 21 goals in 77 games for the Dutch team.
