The Polish keeper has previously hinted that he would be keen on a move to the Premier League.
The 29-year-old told The Daily Record: “I’ve indicated I might want to try my luck in the English Premier League or somewhere else, but I have spent four fun years at Celtic. I love the club and if I play in Glasgow until the end of my career I won’t complain.
“This campaign has begun really well and I want to maintain that until the end.
“There are still a few good years of football left in me and I want to focus and make the most of it. I will concentrate in every match to ensure the mistakes of last season are not repeated.
“I worked hard at training last year but mentally I might have been somewhere else.
“This season I’ve decided to deal with all of that and I’m sorting out my life.”
