The England international has been out of action for 13 months due to knee problems.
“The best is yet to come and I just cannot wait to get back out there,” he told MUTV.
“I will be trying to improve my game and achieve the great success I think we (United) are destined for.”
“To look back at where I was to where I am now is amazing,” he added.
“I just want to be part of it again and have a great season. I cannot wait to pay back some of the faith the fans have shown me.”
