Manchester United hero Paul Parker has questioned the strength, fitness and pace of Ole Gunnar Solskjaer's side.
Parker was speaking after United dropped off during the second-half of their clash with Norwich City, despite eventually winning the match 3-1.
He told Goal: "I had a Ukrainian [Andrei Kanschelskis] train in front of me, and I could play it to his feet. But I could also play it into space as he was quicker than anyone.
"United don't seem capable of running for a whole match like Andrei was, and they don't have the pace and the energy of Lee Sharpe or Ryan Giggs, who would run the whole 90 minutes.
"They don't have players with the physical toughness of Paul Ince, and I won't even mention Roy Keane.
"United's players don't have the same physical strength. Andrei was so physically strong he could do keepy-uppies with a medicine ball."
