West Ham United are keen to upgrade Diafra Sakho's deal.
The Mail on Sunday says co-chairman David Sullivan, who was instrumental in signing the striker from Metz in the summer, has been delighted with the 24-year-old's outstanding start to his Upton Park career.
Sakho has scored six goals in seven games following his £3.5million move which was in the balance until Sullivan revived it.
Sakho agreed a four year deal but Sullivan wants to reward his form and will look at revising the figures in the New Year.
