Manchester United's Wayne Rooney 'injury doubt for Manchester City battle'

Manchester United striker Wayne Rooney is reportedly a doubt for this Sunday's head to head with local rivals Manchester City due to a minor injury.

The England captain, who is due to return to action after serving a three-match ban, is believed to have picked up a knock in training.

According to The Express, the 29-year-old was seen limping heavily during a sponsorship event with his teammates at Old Trafford on Monday.

Rooney missed United's victory over Everton and draws with West Bromwich Albion and Chelsea after receiving a straight red card in the Red Devils' 2-1 win over West Ham United last month.

United are currently eighth in the Premier League table, four points behind third-placed City.
