Such are the standards this group have set this season, Clive was in no mood to celebrate a point and said the outcome felt like a defeat.
"It was a situation that we haven't had too much this year in that we have been a goal in front and been pegged back," reasoned the Development Coach. "You know it is possible, we needed that second goal and we had enough opportunities, but we didn't kill it off.
"We paid the price for that and it feels like a defeat because we should have won the game and closed it out - but we didn't. It is another part of the learning process and what is expected of them when you are in a position like that.
"It was very disappointing to concede a late goal.
"The conditions were very poor, but we played some good football without being clinical in the final third. We needed that second just to close the game out."
Clive Allen was disappointed not to make it six wins in a row to mark his side's title success on Monday evening against Crystal Palace.
