Entering the finale in third place, Chelsea knew that a win would guarantee a place in Europe's flagship competition next season and avoid heaping more pressure on their Champions League final against Manchester City next season, when they would have been relying on victory to qualify again had they finished outside the Premier League top four.

2-0 down at Aston Villa and with the pretenders for their place in their top four, Liverpool and Leicester, both winning, Chelsea were heading for a frustrating fifth-placed finish that would only have secured a Europa League place on the merit of their league position.

Rivals Tottenham came to the rescue, forcing goalkeeper Kasper Schmeichel into an own-goal to make it 2-2 with less than 15 minutes of normal time remaining in their season swansong.

At that stage, Chelsea were heading for the Champions League by virtue of having a two-goal superiority on goal difference against Leicester, who they were level on points with.

The unlikely Chelsea saviour of Gareth Bale, the Real Madrid superstar who has returned to Spurs on loan, then scored twice late on at the King Power Stadium to put the Blues a point clear in the race for fourth and ensure the Foxes fell out of the top four as the full time whistle blew on a surprisingly nerve-wracking afternoon for manager Thomas Tuchel and owner Roman Abramovich.

In an underwhelming performance that did not bode well for their clash with champions City in Porto, captain Cesar Azpilicueta was sent off late on for a daft altercation with England midfielder Jack Grealish.

Liverpool finished third by beating Crystal Palace 2-0 at Anfield in a result that did not matter to Chelsea because of Leicester's loss.

"We're in the Champions League next season so we have to be happy," defender Ben Chilwell told Sky Sports, speaking after the 2-1 defeat at Villa Park in which he pulled a goal back in the 70th minute.

"We were nowhere near good enough today, we have to take that. It's been a difficult, long year for every team.

"It's not how we would have wanted today – we were nowhere near our best – but we have to take it.

"We created chances during the whole game and didn't put the game to bed when we should have. I don't know how many chances [Villa] had but it seemed like they scored with their only two chances.

"They played well and we didn't but we're in the Champions League so that's a great feeling."

Chilwell admitted Chelsea were "angry" at half-time and felt they should have been winning.

"It was literally all to play for today," he reflected. "It's not down to ourselves – thankfully it's down to Spurs but we're through and that's the main thing."

While fans watched in horror as their side slipped out of the top four for the majority of the 90 minutes, Chilwell said Chelsea's players were not informed of their predicament.
