The goal, even if a tad fortunate, only seemed to spur Palace on. Eze again very nearly made it 2-0 only a minute after the opener, dragging a low shot just wide of the post.
Daniel Muñoz then managed to get on the end of another well-worked set-piece, flicking the ball towards the Fulham goal only for a last-ditch clearance to deny the Eagles.
It was a controlled opening 45 minutes from Glasner’s team, who were good value for the lead. Hughes played the ball forward to Eze, who managed to flick the ball round the corner and into the Fulham box.
Mateta did the rest with a cool finish beyond Leno, celebrating in front of a bouncing away end. Sadly, VAR cut short the celebrations, with the Frenchman ruled to be marginally offside, although it was tough to tell either way in real time.
Despite that blow, Palace continued to pile on the pressure. Another Hughes corner nearly provided the Eagles second of the afternoon.
This time Lacroix got clean contact but Leno kept it out, before Lerma’s volley from close range was well blocked.
Eze was also still causing problems every time he got the ball, with one excellent charge down the left wing nearly resulting in a goal for Mateta, only for Leno to intercept the cross.
Eventually Glasner’s side would make their pressure tell. A flying counter-attack saw Mateta charging towards the Fulham defence with Palace shirts to his left and right.
He chose to pass to his right, with the ball reaching wing-back Muñoz. Keeping his calm, he took a clever touch before slamming the ball home from a tight angle in front of a jubilant away end.
