Mason Mount has signed a new five-year contract with Chelsea.
Mount, who spent last season on loan at Championship club Derby County, has long been tipped for a bright future by those at Stamford Bridge.
“It's a massively proud moment for myself and my family," said Mount.
“I'm really looking forward to the coming season now and working hard to have an impact here at Chelsea. I've been at the club for a long time already and hopefully I'll stay for a long time to come."
Mount scored for Chelsea in their 4-0 pre-season victory over St Patrick's Athletic in Dublin on Saturday and is now heading with the squad to Japan ahead of matches with Kawasaki Frontale and Barcelona.
