Jurgen Klinsmann - Tottenham
The German striker was 30, just a year younger than Gareth Bale is now, when he won a place in Spurs fans' hearts in the 1945/95 season. He scored 21 goals and won the Football Writers' Player of the Year award, before leaving for Bayern Munich. He came back in 1997/98 and scored crucial goals to help save the club from relegation - a rare example of a player succeeding during both stints at a club. What would count as success for Tottenham this season with Bale back? They're 9.89/1 to finish in the top four.
Robbie Fowler - Liverpool
Robbie Fowler burst into the Liverpool first team as an 18-year-old in 1993, scoring five goals in a League Cup tie against Bolton. He scored 12 times in his first 13 appearances and was dubbed 'God' by the Kop. He averaged better than a goal every other game before he left Leeds. He subsequently joined Manchester City where he struggled with injuries. Everyone, including Fowler, was stunned when Rafael Benitez brought him back to Liverpool on a free transfer in 2006. He featured rarely second-time around, even though he was only in his early-thirties, and left for Cardiff in 2007.
Thierry Henry - Arsenal
Under his compatriot Arsene Wenger, Thierry Henry became Arsenal's all-time leading goalscorer in eight glorious years at the club, which included two Premier League titles, two FA Cups and four Premier League Golden Boot awards. He was also runner-up for the Ballon d'Or. He left for Barcelona in 2007 after a protracted flirtation with the Catalan Giants. He did ok there but the Gunners had the best of him and, while Henry was playing for New York Red Bulls, Wenger brought him back for a couple of months in 2012.
On the face of it, his return to Arsenal looks like a nostalgia trip but he actually scored the winning goal in two matches and certainly did his standing there no harm.
Sol Campbell - Arsenal
What is it about north London? Here we are once again talking about a club legend returning for a short spell in the twilight of his career. Campbell was a stalwart of the Gunners' defence during the Wenger years - after controversially signing from Spurs in 2001 - and widely hailed as one of the best defenders of his generation. He went on to have three successful years at Portsmouth before an ignominious short spell as Notts County's player manager. That was followed in 2010 by a shock return to Arsenal. In six months, he made 14 appearances and scored in a Champions League match. Not bad.
Wayne Rooney - Everton
When Wayne Rooney broke into the Everton first team in 2003, the Toffees thought they had a player who would dominate world football for the next decade. They also knew he wouldn't be staying with them for long and so it proved as Rooney departed for Manchester United in 2004. In 2017, he returned to Goodison, claiming he'd worn Everton pyjamas for the previous 13 years. The strange thing about Rooney's second spell with Everton is that, although it only last one season, it actually went pretty well. The high point came when he scored a hat-trick against West Ham which included one of the most exquisite strikes of his career.
