Andriy Yarmolenko's 89th-minute winner earned three precious points for West Ham United in a 3-2 success over Chelsea.

The loss is Lampard's sides first after their impressive run since Project Restart. The Hammers had not won a game since after the break and looked forward to salvaging the three points on home soil to elevate their position from the button part of the table.

Christian Pulisic went close for the visitors before Tomas Soucek's effort at the other end on 34 minutes was ruled out for offside.
