Iron boss Graham Alexander says his side should have won Tuesday night’s game with Charlton Athletic, which ended in a 2-1 defeat.
Kevin van Veen’s second half goal had drawn United level, but a last gasp penalty converted by Tony Watt saw the Iron fall to their third straight loss.
“We had more than enough opportunities to score more than the one goal to put the game to bed,” Alexander said.
“We should have gone on to win it because we had more than enough possession and attacking opportunities to create chances.
“The keeper has made an unbelievable save off Paddy then got the goal we deserved and then camped in their half for the rest of the game.
“It is a game we could and should have won and it is a cruel one to take.”
