Nottingham Forest recorded their first away Premier League win of the season as they beat bottom-of-the-table Southampton to move out of the relegation zone.
Forest had only scored one league goal away from home before this match but were gifted a 27th-minute lead.
Lyanco carelessly lost possession on the halfway line with Brennan Johnson capitalising and racing clear before he pulled it back for Taiwo Awoniyi, who buried the chance.
Southampton are in their 11th successive top-flight campaign but have now only won once in 13 in the league since beating Chelsea 2-1 on 30 August.
The Saints failed to have a shot on target and are yet to pick up a single point from four matches since Nathan Jones replaced the sacked Ralph Hasenhuttl in November.
Meanwhile, improving Forest have now lost only two of 10 games in all competitions and, as it stands, are set to move above West Ham, Everton and Bournemouth from 18th to 15th.
Che Adams had a glorious chance to put the hosts ahead after only six minutes but shot wastefully wide from inside the penalty area.
That proved costly as Forest, with just two points from their previous eight games on the road, hit the crossbar through the impressive Johnson before he set up Awoniyi 15 minutes later for the opening goal.
The first half got even worse for the hosts when centre-back Armel Bella-Kotchap, a member of Germany’s World Cup squad although he failed to make an appearance, went off injured after only 34 minutes with Duje Caleta-Car replacing him.
The atmosphere was turning with Southampton giving their fans little to cheer for the remainder of the half, with the team booed off at the break.
Sekou Mara had a rare chance for the Saints in the second half but headed wide, although it took a deflection and was wrongly given as a goal-kick.
Jones made an attacking triple substitution in the 64th minute, with Joe Aribo, Samuel Edozie and Adam Armstrong all coming on, but none failed to test Forest goalkeeper Dean Henderson.
Forest then handed a debut to Brazil international midfielder Gustavo Scarpa after he became the club’s 24th signing of the campaign when he joined Forest on a free transfer from Palmeiras last month.
The visitors were happy to defend deep with Willy Boly, Joe Worrall and Serge Aurier all superb for Forest as they frustrated the hosts.
Southampton could not find a way through and suffered their sixth successive league defeat – their worst run since an eight-game losing streak in 2021.
