#3 Oscar - Chelsea to Shanghai SIPG (£60 million)
Oscar, the young Brazilian was signed by Chelsea in 2012 and was immediately given the number 11 shirt, which was previously worn by Didier Drogba - naturally expectations were sky high.
He announced himself at Stamford Bridge after scoring two wonderful goals against Juventus in a Champions League group stage match.
He stayed at Chelsea for four years but never quite justified his talent. He showed occasional flashes of brilliance, but inconsistency always proved to be Oscar's bane. He played a total of 203 games for Chelsea scoring 38 goals and supplying 37 assists.
He was tempted by the big money offered in the Chinese Super League and Shanghai SIPG snapped him up in January 2016 for a fee of £60 million. During his time at Shanghai till now he has played a total of 40 matches contributing 9 goals and 17 assists.
