Reviewing five most expensive Premier League transfers that didn't pan out well

2. Sergio Aguero – Athletico Madrid to Manchester City, £38 million

He will be forever known as the man who brought the title to Eastlands, but does that define Aguero’s City career to this date?

In his first season, he scored an impressive 30 goals, including that title winner against Queens Park Rangers.

However, things went downhill for Aguero last season as he managed to hit the back of the net only 17 times. It is too early to judge his career in England, but he will need to improve from last season to show he is worth the money City paid.
