Neil Lennon’s men have struggled so far in their off-season matches, failing to score in three of four outings during their stint in Germany and Holland, before losing 4-0 to Dutch giants Ajax on Sunday.
Ahead of the Parkhead meeting with the Canaries, Forster is aware that Chris Hughton’s men will be a very difficult opponent, especially after their good showing in England’s top flight last season.
"I think there will be a bit of pressure on us playing at home, so we will have to go out and play well,” he told the club’s official website.
"It will be a good game for us to play in and it will be a good test.
"It will be important we turn up and play because it will be a tough game.
"I'm sure Chris Hughton will have got them all going and it's important for them to start the season well.
