Owen Hargreaves says the atmosphere at Old Trafford is the best he's experienced.
The Manchester United midfielder told United Radio: "I've been very fortunate to play in some fabulous places. I've played in two World Cups, a European championship, a Champions League final it's very difficult to compare those experiences.
"I leaned over to Giggsy and said 'you must be so happy to have played here for your whole career'. I think Old Trafford helps you feel very strong and it's great to be a part of it."
