The veteran forward, who passed Sir Bobby Charlton to become United's all-time top scorer in January, returned to Merseyside after 13 years at Old Trafford. He thanked everyone for making his time in Manchester so memorable:
The 31-year-old broke through as a youngster at Everton before moving to United in 2004. As a Red Devil, he won five Premier League titles, one UEFA Champions League trophy and one UEFA Europa League championship, as well as a number of domestic cups.
He led United's attack for years, but his scoring output came down after the 2011-12 campaign. Several managers used him as a midfielder and even in a wide role, but none of the changes helped him rediscover his shooting boots.
Both sides needed something different, and the Toffees made for a perfect match, per Samuel Luckhurst of the Manchester Evening News:
Rooney will undoubtedly remain a United legend regardless of what happens at Goodison Park, and one or two more great seasons with Everton would add to an already impressive legacy. While he's been a Premier League star for well over a decade, he's still just 31, so he should have plenty left in the tank.
