The former Hammers striker has been very impressed with the performances of the Senegalese striker.
It is not the first time the Senegalese striker has popped up with an important goal this season and is not likely to be the last, so he has certainly proven to be a shrewd buy from Metz in the summer.
One man who is clearly impressed with the player is a former West Ham striker himself.
Tony Cottee played for West Ham in two separate spells in his career, scoring nearly 150 goals in his time with the club – so he knows a little something ab out scoring goals for West Ham.
And he told London 24 today about how impressed he has been with the new signing:
"Diafra Sakho has been excellent all season. He had trouble with the African Cup of Nations, but when he has played he has always looked capable of scoring goals and when you consider he only cost £4million, it is difficult to think of a Premier League player who has been a bigger bargain.
"The last time we paid that money for a striker we got Modibo Maiga, so it just goes to show!"
Sakho has indeed been impressive. He has scored 12 goals in 24 appearances for the club this season.
When you also consider that he only cost a small fee, reported by the The Guardian to be in the region of just £3.5 million, he has truly proven to be one of the bargains of the season.
