The keeper knows that experience counts for everything as they prepare to take on Portsmouth at Old Trafford on Saturday, a games that could see United go back to the top of the table and apply the pressure to Chelsea.
"Experience definitely helps," The 39 year old told www.manutd.com.
"You've been there before - through narrow escapes and must-win games. You know how to handle them. The more you go through these situations the better you are at dealing with them.
