Manchester United have drawn three of their last four games 0-0

Former Manchester United midfielder Paul Scholes has continued to criticise his old team's performances under manager Louis van Gaal and suggested that even Sergio Aguero would 'struggle' to score in his system.

The Red Devils have drawn three of their last four games in all competitions 0-0 and the outspoken Scholes is not happy.

Serving as a pundit for BT Sport during Tuesday night's Champions League coverage of United's game against CSKA Moscow, the 40-year-old said: 'It's just a sideways, possession-based, boring style of football. Does he have a problem with forward players?'

Despite a goal against CSKA, United striker and captain Wayne Rooney has come under scrutiny in recent weeks, but Scholes believes that the service to him has been poor.

The ex-England international added: 'We talk about Rooney getting all the stick, but I don't think anybody would score goals in this team as a centre forward. I think Sergio Aguero would struggle.'

Scholes also feels that Van Gaal made mistakes in letting several of United's attacking players leave the club in the transfer window.

He remarked: 'Look at the players that he's let go: (Robin) Van Persie, (Danny) Welbeck, (Javier) Hernandez, (Adnan) Januzaj, (Angel) Di Maria. I'd love to see these players at the club now.'
