Diafro Sakho wants to secure a transfer from West Ham by the time pre-season training starts, according to a report.

Sky Sports claim the 26-year-old wants clarity on his future after Sunderland tabled an £11million bid for him on Friday.

It is said that Senegal international Sakho would like to start pre-season with the club he will be playing for next season.

Most Premier League clubs are scheduled to return to pre-season training in either the last week of June or first week of July, although players competing in Euro 2016 or the Copa America will be given three weeks’ rest after playing at the tournament.

Sakho has been targeted by Sunderland manager Sam Allardyce, who knows the player well after signing him for West Ham from French side Metz in the summer of 2014.

The Senegalese forward scored 12 goals in his first season, finishing as the club’s top goal scorer, but had a more frustrating campaign under Slaven Bilic.

Sakho scored seven goals in 24 appearances and struggled to cement a regular starting position following the return to fitness of Andy Carroll in the second half of the season.

In other West Ham news, the Hammers have made a £11.4million offer for an Argentine playmaker who could rival Dimitri Payet for a starting place.
