Substitute Marcus Rashford struck in stoppage time to earn Manchester United a dramatic 1-0 win over West Ham United at Old Trafford and lift them into the top four for the first time since October.
There were few clear-cut chances in the opening 45 minutes, with a cross by Bruno Fernandes narrowly evading the head of Cristiano Ronaldo.
After the break, United upped the pressure, with Alphonse Areola saving from Fred before Raphael Varane headed over.
At the other end, Tomas Soucek's header from a corner flashed narrowly wide, while David De Gea made a late save from Michail Antonio.
In the third minute of added time, Rashford arrived at the back post to convert a low cross from fellow substitute Edinson Cavani.
United leapfrog West Ham into fourth on 38 points, with the Hammers a point and a place back.
