Raheem Sterling has announced he's leaving Manchester City ahead of moving to Chelsea.

The 27-year-old's £50m move to Premier League rivals Chelsea is expected in the next 24 hours.

The England forward issued a heartfelt goodbye message to his former team-mates and the club's staff and fans on his social media account.

"I arrived in Manchester a 20-year-old. Today, I leave as a man," said Sterling.

"Seven seasons, 11 major trophies, a lifetime of memories."

City signed Sterling from Liverpool in a £49m deal in 2015. He went on to score 131 goals in 339 games, winning four Premier League titles.

Capped 77 times by England, Sterling will become Chelsea's first major signing since the Todd Boehly-led takeover.

He added: "I am thankful for the ups and downs, as it's the downs that have tested my strength and resolve and enable me to stand here in front of you as the best possible version of myself."

Sterling will now link up with the Chelsea squad who flew out for their pre-season tour to the United States on Saturday.
