Darnell Furlong was judged to have handled the ball in the 18-yard-box when striker, Wilfried Zaha, sent in a cross that hit his arm and after a long VAR review, the referee pointed to the spot.
Here are some of the key points from the game:
West Brom's lack of confidence in front of goal:
Throughout the whole game, West Brom struggled to really test Vicente Guaita in the Palace goal, managing one shot on target all game. There was a lack of creativity and movement from the Baggies, and Crystal Palace limited them to half chances that their opponents failed to dispatch.
Conor Gallagher started positively for West Brom when the ball was headed down to him in the fifth minute, but the English midfielder failed to hit the target and this seemed to affect him for the rest of the game.
There were chances from range and chances in the box for the midfielder but all of these chances lacked quality, with too much or not enough power in his shots.
Matheus Pereira and Matthew Phillips had chances to equalise for the Baggies, the latter putting a volley high into the seats behind the goal after Patrick Van Aanholt misjudged the flight of a cross. Pereira pushed for a goal and put some great crosses in but Guaita was equal to his style of play
Conor Townsend hit a shot from the edge of the box near the end of the game and it span away from goal and stayed on the pitch, which really sums up their performance at Selhurst Park.
The VAR penalty incident:
Crystal Palace were struggling for possession and they were being pressured and penned back by their opponents, who looked more likely to break the deadlock. However, in the 33rd minute, Wilfried Zaha's cross hit Darnell Furlong's arm.
There were shouts from the Palace players but the referee looked more than happy to carry on with play. The video assisted referee looked at the incident, slowing it down to see whether or not the defender handled the ball. The video assisted referee looked to have made their decision on the incident but then they focused on whether Zaha was offside in the buildup.
From the previous freekick, VAR drew their lines out and determined that the striker was just onside. They proceeded to instruct Simon Hooper, the on-field referee, to go to the screen on the side of the pitch, with the official ruling against his initial decision and awarded a penalty
This looked to be the correct decision when the replay was slowed down, as Darnell Furlong looked to move his arm towards the ball to try to control Wilfried Zaha's cross. The ball was down low and the cross looked to be a couple of yards away from the defender, which looked to be determining factors in the decision.
This was a big decision that the referee had to make at a crucial point in the game and it looked like VAR helped to make the right decision in this case
Wilfried Zaha is back!
The 28-year-old striker started this first game back after suffering an injury against Newcastle United in February. Although the striker had a substitute appearance off the bench against Tottenham last week, Zaha was allowed to make an instant impact this time round.
He started creating some great runs for his team, looking to create and get forward for the Eagles. He also had personal battles with his opponents, showing his strength against Okay Yokuslu early on in the game.
He was always looking for his teammates in a positive position, finding Jordan Ayew on the edge of the box after being forced wide, but his teammate misjudged the ball as it rolled to him.
He played a sublime ball through to Christian Benteke in the second half, who ran forward but he was dispossessed before he could shoot at goal by Kyle Bartley in defence.
He also won vital free-kicks throughout the game, which broke down their opponent's style of play at important points and a couple of these free-kicks allowed chances at goal.
From a side registered two goalless draws in a row, the creativity and attacking prowess from Wilfried Zaha will be a very welcome addition to the side, who now sit in 11th place in the Premier League.
