He came to the Premier League an unknown, he left a cult hero.
The left-field hero of young sensation Erling Haaland, Michu was signed by Swansea for the 2012/13 season. He was an instant success and ran riot in the Premier League in his first season, with his 22 goals in all competitions securing Swansea a 9th placed finish and a 5-0 League Cup final win. He even earned a solitary Spain cap in October 2013, starting in a 2-1 win over Belarus in a 2014 World Cup qualifier. Ironically, Swansea fans were underwhelmed when the £2m signing was unveiled after the club had lost Gylfi Sigurdsson, Joe Allen and Scott Sinclair in the same window.

However, just as quickly as he became a striking sensation, injuries ravaged Michu. The Spanish striker only managed two more Premier League goals after his first season. It was agreed that his Swansea contract would be terminated in November 2015 and he would retire less than two years later, aged just 31. A tale of a career snatched away far too early and perhaps the definition of a one season wonder, even if it was down to injuries.
The flash in the pan nature of his Premier League career is what makes his story so remarkable. He came, scored two goals on his debut, and then never looked back until the season end. His signature celebration of cranking his hand by his ear had was a frightfully regular sight in that one glorious campaign for Michu and Swansea. A celebration that has since been replicated by his biggest fan, Haaland. Is Michu the best ‘one season wonder’ in Premier League history?
