Chelsea have confirmed the signing of Monaco midfielder Tiemoue Bakayoko, in a deal said to be worth close to £40m.
Bakayoko, a physical and athletic central midfield player, has reportedly signed a five-year contract at Stamford Bridge and will join up with France international team-mate N'Golo Kante.
Bakayoko expressed his delight with the move, "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 teammates."
Chelsea's technical director Michael Emenalo added, "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 Chelsea's third signing of the summer so far after the arrivals of backup goalkeeper Willy Caballero from Manchester City, and centre-back Antonio Rudiger from Roma.
