Hargreaves confident Man Utd will keep nerve
"As long as we're controlling our destiny I don't think we need worry too much," he told MUTV.
"We've got 90 minutes to play and it's a great position to be in. We've had no midweek game so we've put in some good training and hopefully we will be ready for the weekend."
The England midfielder added: "To be in this position feels comfortable for me, I've been there before.
"At the start of the season if somebody had offered us one game, just 90 minutes, to win the league, we would have jumped at that. We're in a good position.
"We've worked so hard all season. Not just the players, the staff, and all the time and energy everyone puts in at this club. That's what makes this a special club. So for them, to see us win the league would be a fantastic moment. We'll go out on the pitch on Sunday and give everything we have for 90 minutes."
