Paul Parker: 'Wayne Rooney is being paid £300k a week to play badly'
United now have an abundance of attacking options following the transfer deadline day signing of Radamel Falcao and Parker believes it is the England captain who should make way.
Rooney put in one of his worst performances against Burnley last weekend, prompting Parker to question how the 28 year-old can justify his £300,000-a-week salary.
In his Yahoo! Sport blog, Parker wrote: "Wayne Rooney has been awful. There he was at Burnley this weekend, supposedly captaining the team - but I saw a player interested only in himself, doing nothing to try and lift his game or inspire his team-mates.
"The only thing in any way remarkable about his performance is that he collects £300,000 a week to play that badly.
"Once Van Persie is fully-fit again, Rooney must be the person to be dropped from United's new attacking line-up: for me, it'll be RVP and Falcao every time. And though there's lots of talk about him playing in the hole behind that front two, I think that would be a huge mistake - why would you have Rooney there when Juan Mata or Angel Di Maria would do the job so much better?"
Rooney was made captain by United manager Louis van Gaal over the summer but Parker is confident the Dutchman will not be afraid to make such a call.
"It'll leave Van Gaal with a big call to make: dropping Wayne Rooney," he added. "He's always shown in his career that he's not afraid of the big decisions; he showed it most recently with his goalkeeper substitution for the shoot-out at the World Cup, and he'll have to show it once again because the way things are looking there will be no place for Rooney in that starting line-up soon."
Rooney, meanwhile, is currently preparing to lead England against Norway in Wednesday night's friendly at Wembley.
However, the striker has been branded a "bit chubby" by defender Vegard Forren who says he will not be afraid of his opponent at Wembley.
"Rooney looks a bit chubby," Forren told TV2.no. "England have obviously got good players, but we're looking forward to it.
