Speaking after the match, Slot told the BBC: "It is too short after the game to speak about it but it is never good when a player has to come off. I took Frimpong off because I did not want to be with 10 men, so that injury is fine.
"The other two (Isak and Conor Bradley) we'll have to wait and see. The good thing is that we have a week to go so hopefully we have enough players available to play next week again."
Slot added: "It wasn’t perfect, especially in the last 10 minutes, but we’re picking up points. I think it’s never been as bad as people said but it’s also true that we are definitely not perfect yet. We knew when we made changes in the summer that it would take time."
