Chelsea have completed the signing of Tiemoue Bakayoko from Monaco for a reported £40m deal.
The Frenchman becomes the London Club’s second most expensive signing behind Fernando Torres (£50m).
The 22-year-old will sign a 5-year contract and join up with the team in pre season.
Bakayoko said: “I have grown up watching Chelsea. Signing was the natural thing for me because it is a club I loved very much in my childhood.
“I am now looking forward to evolving under this fantastic coach (Antonio Conte) and alongside so many great team-mates.”
Chelsea’s technical director Michael Emenalo said: “Tiemoue was outstanding as Monaco emerged as one of Europe’s best sides last season and we are delighted to welcome him to Chelsea.
“Despite his young age he already has plenty of experience as a French title winner and having competed in the latter stages of the Champions League, we believe he will add considerable quality to our squad.”
Bakayoko becomes Antonio Conte’s third signing of the summer so far after the arrivals of backup goalkeeper Willy Caballero and centre-back Antonio Rudiger from Roma.
