Paul Ince has compared Anthony Martial to a "fizzy drink" following Manchester United's goalless draw with Wolverhampton Wanderers.
Martial did not register a single shot in Saturday's Premier League stalemate and struggled to get involved.
The France international was tasked with leading the line for United in the absence of Marcus Rashford and lasted the full 90 minutes, despite his lack of impact.
Former United man Ince questioned Ole Gunnar Solskjaer's decision to leave Martial on the field and criticised the 24-year-old for his latest below-par display.
"I can't believe Martial stayed on for so long," he told Premier League Productions.
"I've always called him a fizzy drink. You open a can, it fizzes and then it goes flat. That's exactly what you saw today.
"He shouldn't have stayed on the pitch as long as he did."
Martial has eight goals and three assists in 19 Premier League appearances this season.
