Steven Caulker
Saints signed Caulker on-loan from QPR in the summer of 2015 as Ronald Koeman added another defender to compliment his squad.
However, the Spurs youth academy graduate made just eight appearances before going back to his parent club the following January.
Just a day after returning though, he joined Liverpool on a loan deal until the end of the 2015/16 season.
He only made four appearances at Anfield but was introduced as a makeshift striker in three of those games with Jurgen Klopp searching for late goals.
