Bukayo Saka was Arsenal's match-winner once again and Patrick Bamford endured a nightmare as the Premier League leaders secured a dramatic 1-0 win at Leeds United.

The Gunners would have been braced for a typically energetic start from Leeds, but play was suspended less than two minutes after it started as a power cut was affecting Hawk-Eye and communications between referee Chris Kavanagh and the VAR.

The in-form Saka gave the Gunners a first-half lead with his fourth goal in three matches after the game resumed following a delay of around 40 minutes.

Arsenal rode their luck to secure a seventh consecutive victory in all competitions, half-time substitute Bamford having a goal disallowed and missing a penalty.

Leeds were then awarded another spot-kick in stoppage time and Gabriel Magalhaes was shown a red card for kicking out at Bamford, but referee Kavanagh overturned his decision following a VAR check as the striker had pushed the Brazil defender – who was instead issued with a yellow card – before he lashed out.
