Wayne Rooney has admitted he is uncertain about his new role at Manchester United following Radamel Falcao's arrival to Old Trafford.
The Premier League giants completed a sensational deadline day move for the Colombian international on Monday after agreeing a loan deal with Monaco, with the option to make the move permanent next summer.
Louis van Gaal indicated Rooney will be a crucial part of his plans after handing him the captaincy of the team earlier in the summer but with Robin Van Persie and Falcao also in his ranks the boss may consider to using the England International in a deeper role.
"I don't know how Falcao's arrival could affect my role," Rooney was quoted by Manchester United official website.
Nevertheless, the 28-year-old has hailed the signing of Falcao, claiming the Colombian striker is one of the best players in the world
"I think it is a fantastic signing. He is one of the best players in the world and it is a real show of intent by Manchester United.
"It is a thrill. We have an exciting team. I am looking forward to the challenges ahead and I want to be successful."
Rooney is currently with the England squad ahead of the friendly game against Norway before their European Championship qualifier to Switzerland on Monday.
And having replaced Steven Gerrard as the captain of Roy Hogdson's side Rooney is looking forward to a new era after their disappointing World Cup campaign.
"It's a great honour to captain my country and I want to be a successful captain. I will be myself in the captain's role. I am always very demanding of myself in what I expect. Playing for your country, every player has to give their all."
"We have to put the summer behind us. We were all disappointed. We went into the tournament with high hopes and were expecting better than we produced, but we have to move on."
