Martial key to Man Utd buying Antony or Nkunku
Manchester United are interested in signing an attacker this summer.
However, ESPN claims that United have to find a buyer for Anthony Martial if they are to sign a big money attacker.
United have many squad players on the books who may not have a future at the club.
However, Martial struggled on loan at Sevilla in the second half of last season, and is on significant wages.
The source claims United's budget would only allow an attacking signing if someone is sold.
