Graham Potter knows there can be no magic remedies to the situation at West Ham. Still, this was a sobering reminder of just how challenging he may find helping the club to turn over a new leaf. From his first three games in charge: one win and two defeats.No such worries for Oliver Glasner and Crystal Palace. A 2-0 victory at the London Stadium marked their first derby win away from home in the capital since November 2022. Their only defeats since November 9 both came against Arsenal within the space of three days a month ago.West Ham continue to window-shop in the January market for an immediate solution to their striker shortage, caused by injuries to Jarrod Bowen, Michail Antonio and Niclas Fullkrug.The Palace fans in the away end could point to their own team’s forward as an example of just what the Hammers are after right now. Jean-Philippe Mateta scored both goals and led the line adroitly.
