10 Game-Changing Premier League Summer Transfers

For most of us, being 18 years old was a time where we struggled with our new-found legal responsibility to drink in pubs. For Wayne Rooney though, it was a time where he had to cope with becoming the most expensive teenager in football history, and playing for one of the biggest clubs in the world.

This kind of situation must've come as no surprise for young Rooney though. At 16 he made his Premier League debut for Everton, and within two years he was being touted as one of English football's greatest ever prospects. No pressure then, but it was his £25.6 million signing for Manchester United in the summer of 2004 that catapulted Rooney into becoming a household name in football.

Any thoughts that the teenage striker might wilt under a heavy weight of expectation were nullified in his United debut, when he scored an incredible hat-trick against Fenerbahçe in the Champions League. In the years that followed, Rooney became United's record goalscorer, and he's won every major football trophy with the club; a glittering 13 year spell which came to an end this summer as Rooney has gone full circle and returned home to his boyhood club.
