6. Raul Jimenez – Benfica to Wolves
Jimenez’s loan spell at Wolves isn’t much talked about, maybe because he was signed permanently after only one season for a fee of £30m in 2019. In his first season with the club, they had an exceptionally good campaign considering they had only just got promoted. The Mexican scored 17 goals under Nuno Espirito in all competitions that season. It was a breakout season for the 27-year-old as he hadn’t made such an impact with any of his previous clubs. He has been performing pretty well to this day for the Wolves.
5. Robbie Keane – Inter to Leeds
The move of the young Irish from Coventry to Inter was not much of a success so he was sent on loan to Leeds United in the mid of 2000-01 season where he had a pretty good impact instantly, with nine goals in 14 games for the club while they were competing for a Champions League spot. Watching him perform, the Leeds manager, David O’Leary, made his loan deal permanent in May 2001 at an original cost of £12 million, signing a five-year deal.
4. Kyle Walker – Tottenham to Aston Villa
The English international had been loaned out to 3 clubs by Tottenham before getting signed by Manchester City to make him the world’s most expensive defender at that time. In the mid 2010-11 season, Kyle Walker was loaned out to Aston Villa. He had an impact very quickly on the team when he scored just 9 minutes into his debut game versus his former club Queens Park Rangers. His first PL goal was a beautiful 30-yard strike vs Fulham. He played just 18 games for Aston Villa but announced himself to the world during that time. He is, without a doubt, one of the best loan signings in Premier League history.
