Aston Villa manager Martin O'Neill felt Manchester United defender Nemanja Vidic was fortunate not to be sent off as the two sides fought out a goalless draw at Villa Park.
Villa ended a run of 14 successive defeats against the Red Devils and their share of the spoils lifted them into fourth spot in the Barclays Premier League but O'Neill felt Vidic should have been red-carded after a challenge on Villa striker Gabriel Agbonlahor.
"I can understand the concern over whether or not it was a penalty. But it is definitely a foul," O'Neill said. "If we get the foul, the player (Vidic) has to be sent off because it is a goal-scoring opportunity. It is as simple as that."
"I didn't need to look at a TV replay to see that it was a foul - but I did do it and there is no doubt that Vidic fouled Gabby," he added.
Unsurprisingly Sir Alex Ferguson had a different viewpoint of the incident.
He said: "Vidic has got the ball. The crowd can sometimes get you a penalty but the referee couldn't give that one. He gave plenty to them as it was."
Of more concern to Ferguson, was the fact winger Cristiano Ronaldo could miss Tuesday's Champions League game with Villarreal.
The Portuguese star limped out of the game in the closing stages with a leg injury.
Ferguson said: "His leg is in a mess. He is doubtful for Tuesday."
