The Welshman told ManUtd.com he's feeling as fit as ever.
"I felt good against Sunderland," said Giggs. "It was the last game of the season and yet I still felt good.
"So now I'll get refreshed this summer and look to go again next season. Hopefully we'll get a positive result at the end of it. We were so near [to winning the title] this year but sometimes you need disappointments in your career, and your life, to go forward."
