The Red Devils will reportedly have to part with the forward if they want to land the Hammers midfielder
West Ham will demand Anthony Martial as part of any deal which takes Dimitri Payet to Manchester United, it has been reported.
Martial, who has scored four goals in 16 appearances so far this season, was a notable omission as United beat Crystal Palace 2-1 on Wednesday.
And Le10Sport understand that Martial, who arrived at Old Trafford back in September 2015 from Ligue 1 outfit Monaco in a deal worth up to a reported £57.6m, is wanted by the Hammers should United firm up their interest in midfielder Payet.
West Ham have made a slow start to the league campaign and currently occupy 15th in the Premier League table, four points above the relegation zone.
