Asked why he replaced Mateta with Will Hughes, Glasner said: said: "It was a tactical decision. Now, I have to say it was the wrong decision. Not taking him off, but changing the formation to a 3-5-2. We wanted to control the midfield more, but it didn’t work.
"Subbing him wasn’t a mistake, he can do better than he did in the first half. He lost too many duels and balls. That’s why we decided to change something. The mistake I made was to change the system, not subbing JP."
