Jayden Bogle's goal against Bristol City was his second of the month and season

Derby County manager Frank Lampard described his team's win at Ashton Gate as "massive" after they boosted their play-off hopes and seriously dented Bristol City's own top-six aspirations.

Tom Lawrence and teenage defender Jayden Bogle settled the match in Derby's favour, either side of Antoine Semenyo's red card for a poor tackle on Tom Huddlestone.

"At this stage of the season, when you're that close, it's massive," Lampard told BBC Radio Derby.

"It's big, because we know where Bristol City were. [They] put us under pressure at times, but the resilience and the determination of the team was fantastic."

With two matches remaining, Frank Lampard's side remain sixth in the table, above Middlesbrough on goal difference and four points ahead of the Robins, who are eighth - but Boro have played a game more.

The former England midfielder added: "In terms of desire and attitude, I couldn't have asked for any more.

"In terms of our quality, at times I thought it wasn't quite as it could be, because the game needed calming down. Only later on in the game did we get that, when they went down to 10 men."

Bristol City dominated much of the first half at Ashton Gate, both before and after Lawrence's deflected opener for Derby.

Jamie Paterson was denied by Derby goalkeeper Kelle Roos three times in quick succession after the half-hour mark, and he also did well to keep a powerful shot from Josh Brownhill out in the 44th minute.

In an action-packed half, there was still time for Martyn Waghorn to test Niki Maenpaa at the other end in injury time.

The second period started with Roos denying Paterson again and the Rams scrambling Brownhill's follow-up shot off the line.

Bradley Johnson was then denied by Maenpaa before City were reduced to 10 men when substitute Semenyo was sent off.

Andreas Weimann hit the bar for the home side following up an effort that was cleared off the line by Waghorn, and Derby eventually killed the game with Bogle's clincher.

Bristol City head coach Lee Johnson told BBC Radio Bristol:

"It's a really tough one to stomach because we started on the front foot, and were excellent in terms of attitude. We pressed, we won tackles, we were competitive.

"The first breakaway gets them their goal, so I'm disappointed with that. After that, [we had] a fantastic reaction, hit the bar, [had one] cleared off the line - you couldn't make it up. It seems to be the way it's gone for us in the last three or four games.

"We are still fighting, but it's not in our hands. We've got to go and do our job now and win our next two games."
