Arriving from Porto in August 2010, Raul Meireles was perhaps Roy Hodgson's most successful signing - but he still left Merseyside within a single season after handing in a transfer request.
The Portuguese midfielder fired five goals in 44 appearances - all of which came in the second half of his spell at Anfield under Hodgson's successor, Kenny Dalglish.
But with his place in jeopardy following a summer bolstering which saw midfielders Jordan Henderson and Charlie Adam arrive at the club, Meireles asked to leave and joined rivals Chelsea minutes before the transfer window closed in August 2011.
His Reds debut arrived on September 12 when he came off the bench in a goalless draw at St Andrew's and the tattooed star blasted his first LFC goal in a 2-2 derby draw versus Everton.
Meireles also scored a stunner at Wolves and a winner at Stamford Bridge.
