Richarlison had given Robert de Zerbi’s disappointing side hope, after Enzo Fernandez and Andrey Santos gave the hosts a deserved two-goal advantage, when Chelsea’s combative left-back Marc Cucurella unceremoniously dragged Spurs defender Micky van de Ven to the floor.
It came as Mathys Tel prepared to take a corner and Spurs demanded a penalty that never came, their disbelief doubled when Cucurella was cautioned over the incident.
Video assistant referee (VAR) checks detected his foul came seconds, maybe even one second, before the ball came into play, meaning a penalty could not be awarded.
Referee Stuart Attwell could only take action against Cucurella with a yellow card, and once VAR confirmed the ball had not been kicked there was no room to initiate a review and subsequent spot-kick.
Former Chelsea and England striker Daniel Sturridge told Sky Sports: “One second difference and it is a guaranteed penalty. Cucurella is so lucky.”
It was the tightest of calls.
Spurs boss De Zerbi refused to dwell on the controversy, but said the Everton game was arguably “more important” than the club’s Europa League final against Manchester United last season, which they won in Bilbao.
He added: “It is not my business. My business is to focus on preparing the next game and to get the points we need because Sunday is the final for us.
“This game is important, more than playing for a trophy. Last season ended with playing for a trophy. We play for something more important than a trophy because of the pride and history of the club.
“You can win a trophy but it does not change anything. The most important thing is the pride and dignity of the club, so that we can go on holiday in the Premier League.
“We have to stay alive. Sunday against Everton is a big day for us.”
