Manchester United manager Sir Alex Ferguson hopes his team's stoppage-time lapses against Everton will not have a major bearing on the title race.
United led 3-1 at Goodison Park as the match moved into stoppage time only for Tim Cahill to head home before Mikel Arteta's deflected strike made it 3-3.
Ferguson's side had conceded a late goal in their last game, a 2-2 draw at Fulham, and the veteran United boss admitted: "It's amazing. We've thrown it away, like we did at the Fulham game.
"You have to have determination in situations like that. We were so wasteful with our chances. We could have scored five or six in the second half with great opportunities and that has come to haunt us.
"But saying that, to lose two goals in injury time is unthinkable. We had it under control and the game is finished - even when they scored a second. It is a terrible end for us.
"We've thrown the points away and hopefully at the end of the season we don't sit back and regret it.
"We had some great opportunities in the first half and I think most of the time we were the team who threatened most in terms of playing football.
"Vidic's goal was a good time to score but going 3-1 up you think you are in a comfortable position but football comes back to bite you. It has happened before and we have done it ourselves."
