#1 Luis Suarez (Ajax to Liverpool: January 2010)
The best January deadline day signing (EPL) hands down, Luis Suarez made a £22.8 million move from Ajax to Liverpool to replace departing Kop Hero Fernando Torres. Suarez did more than just replace Torres, almost dragging Liverpool to the Premier League title in a thrilling 2013-14 season where he even won the PFA Player of the Year award.
Known for his direct running, finishing and dribbling ability, Suarez tormented Premier League defences and tore apart opposition defences with ridiculous ease. Although his tenure was slightly tainted by the biting and racial abuse incidents, there was no denying the impact at the Uruguayan had at Merseyside.
Finally, Suarez made a move to Barcelona for a fee of £64.98 million in June 2014 earning Liverpool a whopping profit of £42 million from his sale. While Suarez earned only one League Cup during his time at Liverpool, he is still considered by many as one of the greatest Liverpool players in the Premier League era.
