Leeds United failed to restore their three-point lead at the top of the Championship table, as they slipped to a surprise 1-0 defeat at Portsmouth on Sunday.

The pressure was on Daniel Farke's leaders after victories for Sheffield United and Burnley on Saturday, with the second-placed Blades moving level with Leeds and the third-placed Clarets drawing within two points.

But Colby Bishop struck just after the hour mark to drag Portsmouth 10 points clear of the relegation zone, inflicting Leeds' first league loss since November.

Leeds arguably should have had a penalty in the 10th minute as Matt Ritchie kicked through the back of Dan James' leg inside the area, but referee Rob Jones was unmoved.

Both teams struggled to create chances throughout the first half, but Portsmouth were indebted to Nicolas Schmid for keeping it goalless after 38 minutes.

He got down to his right to parry Manor Solomon's drive, then sprang back to his feet to deny Joel Piroe and make it a remarkable double-stop.

Piroe had an even bigger chance five minutes into the second half, but he lifted his shot over an open goal, after Solomon rounded Schmid to put it on a plate for his team-mate.

And Leeds were punished for that miss when Bishop darted onto Connor Ogilvie's ball down the channel, before taking advantage of some hesitant goalkeeping from Illan Meslier to produce a dinked finish.

Junior Firpo had a shot smothered by Schmid as Leeds chased an equaliser, then the left-back crashed a header off the crossbar and saw the rebound turned wide by James.

Josh Murphy almost added a second Portsmouth goal when he struck the post from range, and John Mousinho's men needed another Schmid save in stoppage time, as he turned Sam Byram's header over to preserve their clean sheet.

Data Debrief: Leeds' long unbeaten run over

Leeds entered this game unbeaten in their last 17 league games (12 games, five draws), their best run since going 30 games without defeat under Don Revie between 1973 and 1974, when they finished as First Division champions.

Portsmouth have made Fratton Park a fortress lately, winning nine of their last 12 home Championship games (two draws, one loss), after failing to win any of their first six on their own turf this season (three draws, three losses).
