Tottenham Hotspur manager Thomas Frank has confirmed the club is “dealing with” Yves Bissouma’s behaviour after the Mali midfielder allegedly inhaled nitrous oxide for a second time in as many seasons. 

Bissouma has yet to feature under Frank since being dropped before the UEFA Super Cup clash with Paris Saint-Germain in August for repeated lateness.

The 29-year-old underwent ankle surgery in October, but his hopes of being selected by Frank suffered a setback after a news report showed footage of Bissouma allegedly inhaling nitrous oxide. If confirmed, this would be the second time Bissouma has been involved in such a scenario.

Under English law, nitrous oxide was made a Class C drug in 2023, and possession of ‘laughing gas’ for recreational use is a criminal offence. Frank stated, “It’s an internal matter that we are dealing with at the moment, and when we have dealt with that, then I will comment on it.”

Meanwhile, Tottenham left-back Destiny Udogie will be sidelined until the new year due to a hamstring injury sustained during the 2-2 draw with Newcastle United. Frank revealed, “Destiny picked up a hamstring injury at the end of the Newcastle game, so he’s out until January, unfortunately.”

France forward Randal Kolo Muani, on loan from Paris Saint-Germain, trained on Monday after limping off during Saturday’s 2-0 defeat of Brentford. The victory ended Tottenham’s wait of nearly four months for a Premier League win at home and eased pressure on Frank.

Frank remains focused on the next game, declining to comment on Tottenham’s chances of finishing in the top eight of the Champions League. “I am more about this next game ahead of us,” he said.

Tottenham will face Slavia Prague in their Champions League tie on Tuesday, looking to build on their recent momentum.
