One of the most underrated strikers of last season, Diafra Sakho scored a respectable 10 goals in 23 league appearances for the Hammers. A strong, clinical presence up front, the Senegalese international racked up 98 Fantasy points last season, and should only see that number increase in 2015/16. At the age of 25, Sakho is rapidly approaching his prime, and is expected to only improve upon an impressive debut season in the Premier League. The fact that his only prior footballing experience came in the second and third tiers of French football demonstrates the speed with which the forward has raised his game, and his progress should continue next season. £6.5m could prove to be a monumental bargain.
