Graham Potter raged at Bruno Guimaraes’ goal with the West Ham manager adamant that Newcastle's winner should have been ruled out because Max Kilman was fouled in the build-up.
The Brazilian's goal was enough to secure a 1-0 victory for the Magpies which sends them up to sixth in the table and in the hunt for a Champions League spot.
However, the goal could — and according to Potter, should — have been ruled out for a foul by Alexander Isak.
As Harvey Barnes' cross floated into the box, Isak appeared to push Kilman in the back as the ball floated over the West Ham defender and into the path of Guimaraes.
