ARSENAL SUBSTITUTES: Cech, Lichtsteiner, Maitland-Niles, Elneny, Mkhitaryan, Nketiah, Lacazette

ARSENAL XI: Leno; Sokratis, Mustafi, Holding; Bellerin, Torreira, Guendouzi, Kolasinac; Ramsey, Iwobi, Aubameyang
It took United just four minutes to equalise. Leno did well to save a free kick from Rojo but Herrera was quickest to react and after the ball was sent back into the danger area, Martial had the easy job of firing into the net from six yards out.
