The Red Devils slumped to a seventh-place finish in the Premier League following David Moyes’ doomed reign in charge at Old Trafford.
But former Wales star Giggs, who has taken up the role of assistant manager under Louis van Gaal, insisted that he was felt ready to take the “next step” in his career.
“I’d had bad seasons and disappointing seasons before – last year was bad, yes, but it had no influence on my decision whatsoever,” Giggs told the Daily Telegraph.
“I have never been one to look back. I think, having done the [manager’s] job at the end of last season, that finally made up my mind to retire because I enjoyed it and I knew I was ready for the next step.
“I didn’t miss playing that much, so it helped, in that respect, to clearly make up my mind that I was ready to finish. The way last season went had nothing to do with it really.
“It would have been nice to go out on a high, but that had no bearing on it really. I just hadn’t missed playing as much as I thought I would and I was ready for the next step.”
