The 29-year-old has been struggling with injuries throughout his career at Old Trafford. Brown suffered a thigh problem during pre-season, that has kept him out of action.
But Brown is redy to return in the Carling Cup game against Wolves at Old Trafford on Wednesday.
“It was frustrating not to be able to build on where I was at the end of 2008,” he said.
“Getting injured for the most of last season was not very pleasant but I am used to it I suppose.
“There is no point thinking ‘why me?’ I just get on with it and try to be confident. I am fit at the moment. That is the main thing.”
