Exeter boss Gary Caldwell hailed an “unbelievable” win after his side triumphed 2-1 away at Northampton despite playing the whole second half with 10 men.

Luke Harris steered the Grecians ahead at Sixfields but Ryan Woods saw red for violent conduct after clashing heads with Jon Guthrie on the stroke of half-time.

Northampton dominated possession in the second half but created little and even though Guthrie did bring them level, Exeter claimed all three points thanks to Will Aimson’s 83rd-minute winner.

“It was another brilliant display of character and team spirit,” said Caldwell. “I thought the way we started the game was excellent.

“We were surprised by their team, they showed us a lot of respect and changed formation and they locked onto our box and tried to stop us playing.

“But when we adjusted, I thought we caused them a lot of problems and we scored during that period and we could have scored more goals.

“The game then became a bit loose just before half-time and the sending off changes everything but this team fights and always finds a way and it was another unbelievable win.

“It’s not the first time we have won with 10 men this season and that’s all about resilience and character.”

On the red card, Caldwell said: “I think it’s really soft. There’s a coming together and he goes down very, very easily and the referee couldn’t wait to get his red card out.”

The defeat drops Northampton out of the top half of League One.

Manager Jon Brady said: “I actually thought we started really well. For 10 or 15 minutes we dominated the game, we stepped onto them and we had most of the ball.

“Exeter haven’t lost away from home since Christmas and they got back into it but we really stepped on the gas and we’ve hit the post and had shots cleared off the line.

“The goalkeeper’s put one onto the bar and another shot hits our player on the chest when it was going in so we should have scored two or three in that period, but we gave away a real sloppy goal for the first one.

“They then have a man sent off and they sit behind the ball and we get it back to 1-1 but did we really test their goal enough? Probably not.

“But then we give another goal away. We go to clear the ball and it hits their player on the foot and goes in. It’s disappointing because of course you want to finish with a win at home but it’s still been a brilliant season.”

Garry Monk felt Cambridge showed signs of what they can be capable of in his first match as manager.

Cambridge looked on course to mark Monk’s first match with a victory but Northampton dominated territory in the second half and ensured the points were shared courtesy of Jon Guthrie’s late goal.

The Us moved a point further away from the relegation zone with the 1-1 draw, ending a run of four straight losses and sitting five points above the drop zone with 10 games remaining.

“The positive of it is that we’ve stopped that run of results,” said Monk, whose side had led through Elias Kachunga.

“As much as the aim is the three points, every point will count. So I’m pleased on that side of it from the players.

“Quite understandably in that second half, where you haven’t won for a while and you haven’t got points, that kind of protective mentality comes in where you’ve got the points and it feels close, and then you’re maybe a bit too protective and stop doing what we were doing with the ball and being that threat.

“It allowed Northampton to come much more into the game in that second half. That’s stuff to work on, for sure. I probably expected a little bit of that, but I can’t complain. The players were great.

“I’ve always said that if you can’t win a game then make sure you don’t lose it. They did everything to make sure they didn’t lose that game. We can be better but that first half’s a really good indication of what they can be capable of.”

Jon Brady spoke highly of his Northampton side as they collected a point following a 5-1 loss to Peterborough on Tuesday.

“It has to be a good point,” he said. “It’s a bit of a milestone to get to 50.

“Our remit was to maintain our League One status, then we can breathe a sigh of relief. To do what we’ve done so far, without patting ourselves on the back yet, is a fantastic achievement.

“We’ve had nine out in the last three weeks, one’s a goalkeeper and six are defenders so we’re shuffling the pack all over the place with no consistency.

“There’s some constraints to us and we’re still putting in that performance. I’m really proud of the character of the team.”

Speaking of his message at half-time, Brady spoke of the need for “a lot more purpose, move the ball quicker, a few tactical elements to get round the sides a bit quicker”.

He added: “I thought we did, and we dominated possession and they were hardly in our half.

“Tuesday night was so tough to take, to bounce back like this today even after going 1-0 down shows you huge character.”

Garry Monk’s first game as Cambridge head coach ended in a 1-1 draw with Northampton.

Monk was appointed on Monday after over three years without a management role, and Jon Guthrie’s late header denied him a debut victory.

His Us side went ahead with their first meaningful attack on 16 minutes, Elias Kachunga firing in after neat interplay between Liam Bennett and Jack Lankester.

Northampton almost scored direct from a corner before keeper Jack Stevens punched Marc Leonard’s delivery away on the line, while Kachunga could have added a second when volleying Lyle Taylor’s cross wide with the last action of the first half.

The Cobblers pressed hard for an equaliser after the break, with Liam Moore’s header deflected off target and Ben Fox shooting wide from the edge of the box just before the hour.

Visiting boss Jon Brady was booked by referee Declan Bourne, seconds before his side drew level eight minutes from the end when captain Guthrie beat Stevens to the ball and headed home Leonard’s free-kick.

Peterborough manager Darren Ferguson feels his side are hitting top form again as the race for promotion in Sky Bet League One intensifies after they hammered rivals Northampton 5-1 in the Nene derby.

This was the Posh’s third league win in a row which moved them to within five points of second-placed Bolton, with their current run coming after four straight defeats threatened to derail their push.

Ferguson said: “We had a blip and they’re a young group – if we had gone through the season without a blip, I would have been surprised.

“When you go through bad times in the season, you have to make sure you’re strong enough to go back and improve when you’ve made mistakes, failures and losses because they’re the ones that define the season.

“We had to make sure we got over that and there’s no question the Blackpool game (in the semi-finals of the Bristol Street Motors Trophy) to get to Wembley has really been a huge shift in momentum.

“But then to win three league games, two of them derbies, is a credit to my players.

“It was all-round a very good performance.

“I thought each member of the team and the subs, it was all-round a very confident performance, and it was a very good result.”

Northampton led after nine minutes when Marc Leonard’s cross was headed in by Jon Guthrie, but Peterborough never looked back after Ephron Mason-Clarks’ 25th-minute equaliser from Jaden Katongo’s low ball across.

Kwame Poku’s whipped finish completed the turnaround three minutes later before Joel Randall poked in a third for the Posh after Poku’s mishit ran off Jack Sowerby.

Hector Kyprianou’s header just before the hour effectively made the game safe, with Josh Knight completing the rout five minutes later after Randall’s corner wasn’t cleared.

Northampton boss Jon Brady said: “We’ve got to hold our hands up and that’s a tough night that’s tough to take against your local rivals, but hats off to them, I thought they were excellent.

“I thought the goals we gave away were very soft tonight.

“We started off, we got the goal then conceded two pretty quick goals and it wasn’t good enough thereafter.

“I’m not going to paper over any cracks and we’ve got to hold our hands up, we’ve got to defend better and be more solid in those moments – defensively we weren’t good enough.

“We’ve got to defend those goals so much better and we’ve got to make sure we get it right for Saturday (at Cambridge) and bounce back.

“We were very good earlier on in the season when we beat them at home 1-0, and today we had a bad night and we’ve got to make sure we get it right on Saturday.”

Peterborough moved within five points of the Sky Bet League One automatic promotion places following a 5-1 demolition of Northampton Town in the Nene derby.

The Cobblers actually struck first at the Weston Homes Stadium, but they collapsed in the face of an onslaught from a rampant Posh side who recorded their third win in a row.

Northampton went ahead in the ninth minute when Marc Leonard’s inviting cross following a short corner was nodded in by captain Jon Guthrie at the back post.

But Peterborough were level in the 25th minute when Jadel Katongo played in a terrific low ball that was finished off by Ephron Mason-Clark.

Kwame Poku then completed a rapid turnaround three minutes later when he whipped a shot into the bottom corner and it was 3-1 just before half-time when his mishit came off Jack Sowerby for Joel Randall to finish.

The Posh were relentless in the second half, with Hector Kyprianou heading in just before the hour and Josh Knight completing the rout after Randall’s corner wasn’t cleared.

Northampton made it two wins from their last three League One games with a 2-1 victory over Lincoln at Sincil Bank.

Goals either side of half-time from Jon Guthrie and Kieron Bowie were the difference as Jon Brady’s side inflicted a third straight defeat on Michael Skubala’s Imps.

The visitors opened the scoring after half an hour when Guthrie out jumped Imps goalkeeper Lukas Jensen to head into an empty net from a Marc Leonard cross.

Lincoln began the second half brightly as they went in search of an equaliser with Jack Burroughs denied by Max Thompson in the Cobblers’ goal.

At the other end, Northampton continued to pose a threat on the break and with 58 minutes gone Bowie’s left-footed shot from the edge of the area doubled the visitors’ lead.

Just two minutes later Timothy Eyoma’s close-range header from an Ethan Hamilton corner promised to set up a thrilling finish.

However, any hope Lincoln had of an unlikely comeback ended when Paudie O’Connor was shown a straight red card for a deliberate elbow as Town held on for all three points.
