Opposition view: Wellens curses 'whacky five minutes' after dramatic Sixfields draw
Rob Hunt’s 14th-minute opener was wiped out by two quickfire Sam Hoskins goals early in the second half, but Kieron Bowie’s red card allowed Orient to dominate the final 40 minutes and eventually Shaq Forde struck, scoring in the 96th minute.
"We started really poorly and for six or seven minutes we couldn't get out," said Wellens. "We gave too many set-pieces away but I thought we dominated the next 25 minutes.
"We scored a great team goal and we were on top and I'd be surprised if their goalkeeper wasn't man of the match, but we have a mad five minutes.
"Players make mistakes and you have to ride with it but Northampton's first goal comes from our corner and then it's a horrible deflection past our goalkeeper. We then give away a stupid penalty and within four minutes the game has turned around, but when they went down to 10 men, we totally dominated the game.
"Our decision-making needs to be better in terms of our final pass and our movement. I'm really disappointed because I felt we deserved to win the game but a whacky five minutes has cost us. We need to score more goals and take our chances if we want to get to where we want to be."
