The centre-back has been a mainstay for Fulham over the years, but he has chosen to pursue a new challenge.

The Cottagers recently confirmed that he would be leaving on a free transfer when his contract expires on June 30.

Chelsea have now officially announced his arrival on a four-year deal. He will be contracted to the club from July 1.

He told the club's official website: " Chelsea  is a huge club and this is a full-circle moment."

"I was born three miles away from Stamford Bridge and made my professional debut there.

"I’m very excited and looking forward to helping push the club in the direction we want to go."

Adarabioyo was also on the radar of Manchester United, but the Red Devils were unable to change his transfer stance.

The defender had already given his word to the Blues which meant that United were unlikely to hijack the deal.
