Celtic goalkeeper Craig Gordon was a subject of interest from Chelsea during the January transfer window, as backup goalkeeper Asmir Begovic chose to leave the club.
Celtic rejected two bids of £3 million and £4 million for the keeper, and 34-year-old Scot has opened up on the bid from Chelsea.
“These things happen,” he said.
“You have to go out there and play through it and continue to do what you’ve been doing.
“That gets you in that position where you’re the subject of a bid. It was about doing the job.
“I’ve had that a couple of times in my career where there’s been talk of changing clubs and bids coming in and having to play games during that time.
“It is mentally draining, but you’ve got to do your job and we continued to play well.
“Celtic didn’t want me to go and I didn’t make a big fuss about wanting to leave.
“I wanted to make sure I was doing my job and helping the team to get to where we wanted to go.”
