#4 Angel Di Maria (Real Madrid to Manchester United) – £94.5 million
Coming off the back of some fine performances for Real Madrid when they won the Champions League in 2013-14, Di Maria was expected to be a smash hit at Manchester United, who signed him for a British record fee of £59.7m – 9.5x more than the average player that season.
However, the Argentine struggled under Louis van Gaal, who refused to use him in the role he had excelled at the Bernabeu, despite Di Maria winning the club’s Player of the Month award in September as he scored two and created two more in his first four games. From there, things went sharply downhill and he was offloaded to PSG the following summer for around £44m.
Di Maria is widely considered to be one of the biggest flops in Premier League history, and his form in France has been erratic since his move.
