Derby moved to the brink of promotion to the Championship after a 1-0 win at Cambridge.

Nathaniel Mendez-Laing’s goal shortly before half-time leaves Paul Warne’s side needing one point at home to bottom club Carlisle next weekend to go up.

Cambridge will be safe if they win either of their two remaining games, or if Cheltenham fail to win both of theirs.

U’s keeper Will Mannion tipped Louie Sibley’s corner onto the bar early on, while at the other end Joe Wildsmith saved well from Macauley Bonne in the 15th minute.

Mendez-Laing nearly scored in spectacular style after 38 minutes, seeing his superb curler from nearly 30 yards come back off the bar, but he only had to wait a few seconds before putting the Rams ahead.

Sibley played Mendez-Laing in behind the defence, and he rounded keeper Mannion outside the box before firing into an empty net.

Cambridge came on strong after the break, with Jordan Cousins firing just wide from distance and Ryan Bennett seeing a shot blocked.

Derby head coach Paul Warne is taking nothing for granted despite another shift in his team’s favour in the race for automatic promotion.

A 3-0 home win over Leyton Orient coupled with Bolton’s draw with Portsmouth means the Rams have a four-point lead in second place, although the Lancashire club have a game in hand.

It was vital Derby took maximum points and in front of another 30,000-plus crowd they went ahead in the 10th minute when Kane Wilson pounced at the back post from a Nathaniel Mendez-Laing corner.

Another set-piece led to the second in the 18th minute, with Sonny Bradley volleying in a Louie Sibley corner from close range.

Orient were more of a threat in the second half but the best chances fell to Derby, with Mendez-Laing failing to convert in the 61st minute after racing clear.

Sibley also went close on two occasions before Bradley sealed a convincing victory with a back-post header from another corner.

Warne said: “The lads have done well, scored from three set-pieces and we probably could have scored from open play but it’s just about winning, so I’m happy.

“It’s been a good day but all it does is give us another opportunity. With two games left it’s in our hands again but we’ve got to try and back it up with two more wins to give us a real chance to go up.

“Obviously now it gives us a much better chance, but that’s all it is so we haven’t achieved anything, but it did feel like a good day. The lads performed well. I don’t think Joe (Wildsmith) had a shot (to save).

“Some days it’s difficult to score goals. Today I watched Leeds play, they couldn’t score, last night I watched Leicester and they couldn’t score. When you are at the top of the table it’s difficult to get over the line.”

Leyton Orient head coach Richie Wellens said: “They ran all over us. They are a good team with loads of experience and they just overpowered us.

“The players have been unbelievable this year but they are probably on their last legs and we are asking too much of them with what we’ve got available. We just ran out of steam a little bit.

“The big one was the set plays. We started the game okay but after the set plays in a quick space of time it becomes very difficult.

“I think it’s something we need to improve on next year. We’ve done well but I think with set plays in this division if you can score a lot more than you concede you can get an extra 12 points.”

Derby boss Paul Warne hailed Dwight Gayle’s ability to make “a massive difference” after his first goal for a year helped promotion-chasing County beat Port Vale 3-0 at Pride Park.

The 34-year-old striker, who joined Derby last month as a free agent after leaving Stoke, opened his Rams account to make it 2-0 on the stroke of half-time – just as Vale were starting to cause the home side some problems.

Derby had made a lively start and went ahead in the fourth minute through Louie Sibley, whose shot took a big deflection to beat Connor Ripley.

The Vale goalkeeper denied Derby a second in the 11th minute with a double save from Nathaniel Mendez-Laing and Max Bird and the visitors had a good period before Gayle pounced in the 44th minute.

Ebou Adams provided the cross and Gayle planted a header from 12 yards into the bottom right corner, and Derby sealed victory in the 58th minute through Sibley’s powerful finish.

Warne recognised the importance of Gayle’s first goal since he scored for Stoke on March 4th last year.

He said: “It was nice Dwight got his first goal, I think he’s scored in every league now.

“I’ve said all along you are only ever as good in any game as your goalkeeper and your centre-forward, and if your centre-forward can get a yard in the box and get a goal at a crucial time it makes a massive difference.

“It will give him a right boost, it will do him no end of good. We know he’s rusty but we also know that he can definitely play at this level and he’s another threat for us.

“Some of his touches today were good again and he’s taken a little bit more rust off. It’s obviously great that Dwight scores because all strikers want to score.

“It was nice to get the second goal just before half-time, it made the lads happier in the dressing room but I wasn’t really happy, I was disappointed.

“We had put ourselves under pressure and seemed to panic with three players going for the same ball but I thought in the second half we were comfortable.”

Derby’s win kept them second in League One, seven points behind leaders Portsmouth, while Vale remain deep in trouble at the other end of the table after suffering an eighth defeat in 11 league matches since their last win.

Vale manager Darren Moore said: “We gave ourselves a mountain to climb conceding an early goal. The manner of the goal wasn’t very good but I just thought in the game after we had that early setback we never really condensed the pitch.

“I think the difficult thing was the two goals, one in the first five minutes and then the other just before half-time, that was probably the most disappointing one because 2-0 is a damaging blow.

“There is a little bit of naivety with us, our mindset can be better, needs to be better, will be better because we get some time to work with them on the training ground this week.”

Dwight Gayle scored his first Derby goal and Louie Sibley bagged a brace in a comfortable 3-0 win over struggling Port Vale.

It keeps Derby second in League One and leaves Vale without a win this year and deep in relegation trouble.

Derby made a lively start and went ahead in the fourth minute through Sibley whose shot took a big deflection to beat Connor Ripley.

The Vale keeper denied Derby a second in the 11th minute with a double save from Nathaniel Mendez-Laing and Max Bird before Tom Barkhuizen fired over from eight yards for the hosts.

Vale appeared to have weathered the storm but they conceded again in the 44th minute with Gayle planting a precision header from 12 yards past Ripley.

Ben Garrity headed a Vale corner wide at the start of the second half but Derby sealed victory in the 58th minute when Joe Ward crossed to the back post and Sibley finished emphatically.

Derby could have added further goals while third-bottom Vale failed to register a shot on target.

Louie Sibley’s last-minute winner gave Derby a 1-0 home victory over stubborn Stevenage to boost their automatic promotion hopes in League One.

With top scorer James Collins out with a knee injury, Derby lacked a presence up front but Sibley finally found a way through in the last minute of normal time.

The victory moved Derby three points clear of third-placed Bolton.

It was Stevenage who came closest to scoring in a goalless first half.

Joe Wildsmith missed a corner and Sonny Bradley had to clear off the line in the 31st minute and Wildsmith rescued Derby soon after when the hosts failed to deal with a long throw and the goalkeeper stopped Jordan Roberts’ shot on the turn.

Derby did not register a shot on goal in the first half and they continued to struggle until Kane Wilson surged forward in the 68th minute and played Nathaniel Mendez-Laing in but he fired wide.

Max Bird was denied by a superb Taye Ashby-Hammond save in the 77th minute but Derby struck late on.

Mendez-Laing cut in from the right and set up Sibley who finished first time from 12 yards.
