Manchester United boss Ole Gunnar Solskjaer has explained going with Anthony Martial over Jadon Sancho for their 1-1 draw at Southampton.
Sancho eventually replaced Martial in the second-half.
Solskjaer said: "We wanted to get Antho going, to have call it two more forwards, Anthony to drift into the left and Mason coming inside from the right.
"Mason scores a very good goal, he didn't have one of his best days but he still contributes.
"When Jadon came on, I thought he looked really sharp for the first 10 or 15 mins but then the whole team fell away and in the last 15 mins we didn't play particularly well."
