Rooney not in form to replace 'striker' Martial

Manchester United manager Louis Van Gaal has refused to accept former footballer Roy Keane's criticism over Wayne Rooney, but admitted that his captain is not playing well enough to take striker's position of Anthony Martial.

Earlier, Keane had slammed Rooney, saying he doesn't look mentally sharp and physically strong despite being the top scorer for his side, the Guardian reported.

Lashing out at Keane, Van Gaal said playing well also depends upon game plan and not entirely on the quality and shape of the player.

The Dutchman further insisted that he is quite satisfied with the captain's performance and felt that he is contributing quite well in the team.

United, who played out a goalless draw against PSV Eindhoven in their Champions League clash, are currently second behind Wolfsburg in Group B with one game remaining, and now have to defeat leaders Wolfsburg in their final match next month to secure their spot in the knockout stages.
