Yeah, after Manchester city had their way with a 4-2vl victory against Crystal palace in the premiership, the coach of Crystal palace had to make sure such mistake doesn't repeat itself when they meet again at the FA Cup finals. And it's apparent he kept his promise to Gardiola as seen in the image above where he had to reveal that.
I didn't know that Crystal Palace's head coach said this to Pep Guardiola after Manchester City defeated Crystal Palace in the Premier League. Crystal Palace's head coach will surely be proud of himself because he was able to solve the system and kept his word as he said to Pep Guardiola. Since the Crystal Palace coach stopped Pep Guardiola from using the system, it shows that he has known the weakness of Pep Guardiola. If Pep Guardiola is not careful next season, he may not beat Crystal Palace in the Premier League.
Me neither. Crystal Palace played a defensive game. They had two players marking City players whenever they had the ball. They let Manchester city attack and when the attack failed, Crystal Palace immediately hits them with a counter attack. When you look at the stats, Crystal Palace had the least ball possession and shots but they took advantage of their chances and won the game.
