Substitute Tchaouna picked out the top-left corner for the Clarets' second goal in the 68th minute, as the hosts prevailed at Turf Moor in a battle of last season's top two in the EFL Championship.

Lesley Ugochukwu had earlier opened the scoring, heading home from Kyle Walker's delightful cross just 18 minutes into the clash.

Scott Parker's side had to survive long spells of Leeds pressure, but outfought its visitors before Tchaouna's 30-yard thunderbolt sealed just its second Premier League win of the season, having also beaten Sunderland at home.

Leeds controlled large periods of the contest, but could not turn its superiority into goals, Brenden Aaronson hitting the post and Jayden Bogle somehow firing over from just two yards out as it suffered a fourth defeat of the campaign.

The hosts climb above Nottingham Forest to 17th place and within a point of Daniel Farke's side, which stays 15th after missing the chance to move into the top half.

Leeds has now lost 17 of its past 22 Premier League away games, and failed to keep a clean sheet in 24 of its 25 most recent such matches.

That was despite sending 47 crosses into Burnley's box, the most by any team in a Premier League match this season.
