Murphy said: "It's been a difficult season for me to be honest after last season. It's difficult when you go through that and it makes days like today even more special.
"I haven't played for the last five or six games which has been really disappointing for me, because the last three years I've been used to playing so much.
"That's something you have to live with and get on with it and do things the right way. There's no point doing stupid articles in the paper moaning about it. You just get on with it. I hope with my performance at Old Trafford I've proved a few people wrong for leaving me out."
