Chris Wilder admitted he did not have to do too much to change the Cobblers’ game plan midway through their 5-1 win over Accrington.
Town were forced into a reshuffle when centre-back Ryan Cresswell was sent off after 38 minutes and with the score 2-0 in their favour.
John-Joe O’Toole was sacrificed for Zander Diamond to maintain the back four and the switch worked, with Northampton going on to secure their biggest away win in almost 11 years.
The team played a more counter-attacking style when down to 10 men but Wilder played down his own involvement in that.
“We capitalised on their mistakes in the second half but I always believed that we could score,” he said.
“The tempo we started with was very good and we deservedly went ahead but we got done on one long ball.
“All of a sudden it’s a completely different game but because of the attitude of the players I didn’t have to do a lot of work.
“We’ve got some really good boys in there who really wanted to get a result and showed a good reaction to a setback.
“I’m not saying that we unbelievably opened them up in the second half but the shape of the team was fantastic and we felt in control.”
Wilder had no complaints with the decision to send off Cresswell, who will now miss Saturday’s home game against Morecambe through suspension.
“I think Lee (Collins) has to play the ball forward a bit earlier, maybe because we’re two goals up we’re taking extra passes and playing too much,” he said.
“There’s a debate about whether Cresser should let him go through one-on-one but I think their boy has been a bit clever and let Cress come piling into the back of him.
“There are no complaints on the decision and it took us from a really comfortable position and completely changed the complexion of the game.”
