Chelsea have officially signed Raheem Sterling from Manchester City in a deal reportedly worth £50m.

The 27-year-old has signed a five-year contract at Stamford Bridge.

A four time Premier League winner with City, Sterling is Thomas Tuchel's first signing of the summer.

"I've obviously achieved a lot in my career so far, but there is still so much more to achieve and I'm really looking forward to doing that in a Chelsea shirt, under Thomas' management," said Sterling.

"London is my home and where it all started for me, and it's amazing I now have the opportunity to play in front of friends and family week in, week out at Stamford Bridge. I'm really looking forward to meeting the fans there soon."

He added: "I can't wait to get going now and continue to do my talking on the pitch."
