The 40-year-old played his last Premier League game for United at Old Trafford on Sunday, as he plans to hang up his boots this summer.
He told Sky Sports: “You always have second thoughts.
“But now I am looking forward to Saturday (against Barcelona in the UEFA Champions League). Let’s make sure we win.”
“It’s been a great six years. To play for a team like this at my age is unbelievable,” concluded the keeper.
