San Jose - Wayne Rooney, who led the line in a 4-2-3-1 formation for 45 minutes against Club America in Seattle on Friday, is relishing the chance to stake a claim to the striker's role.
"My best position, and I have always said it, is as a striker, getting into the box," Rooney told British media.
"And the two seasons I have really done that as a lone striker have been my two best goalscoring seasons.
"It is where the manager and myself see my best position.
"Hopefully I can get a good run of games and repay the manager and score goals for the team, but it is obviously on me to do that.
"I have no doubts that I can score 20 goals or more again and I am ready to take on that mantle and be the one who gets the goals for this team.
"If I play up there again this season, then I can get the goals. It is where I like and it is where I will play."
Rooney has set himself a target of scoring more than 20 goals for United this season after finding the net just 14 times last year in all competitions, his lowest return since joining United from Everton in 2004.
The 29-year-old believes his goalscoring record for England suggests he will provide United with a potent threat following the departures of Robin van Persie and Radamel Falcao.
"I have played different roles over the years for United, but you only have to look when I play for England as a striker, I score goals," Rooney said.
"I hope to score 20 or more goals again this season. If I am playing as a striker, I will be disappointed if I cannot that do that.
"The last time I really played the full season as a striker was 2011-12. All the other seasons, I have been up front, then in midfield or out wide, so hopefully I will stay up front."
