Chelsea battled from 4-1 down to claim what could be a valuable point with a 4-4 draw against Ajax in a thrilling match at Stamford Bridge.
But the Blues may feel like they should have won the game as the visitors were reduced to nine men, while Cesar Azpilicueta had what he thought was the winning goal disallowed following a VAR check.
The blistering start set the tone for the epic with two goals inside the first five minutes – Jorginho’s penalty cancelling out a second-minute own goal by Tammy Abraham.
Ajax then raced into a 3-1 lead through Quincy Promes’ goal while Kepa Arrizabalaga could do nothing when Hakim Ziyech’s corner struck the post before hitting the goalkeeper in the face and into the net.
Donny van de Beek put the visitors 4-1 up ten minutes into the second half but Chelsea then clicked into gear when Azpilicueta pulled one back.
Daley Blind was shown his second yellow for a late tackle on Abraham and Chelsea were awarded a penalty shortly afterwards which then saw Ajax were reduced to nine as Joel Veltman received his second caution for handling the ball in the box.
Jorginho stuck it away and Frank Lampard’s men were level soon after when Reece James smashed home a loose ball.
Cesar Azpilicueta thought he’d made it 5-4 but the goal was disallowed as Abraham handballed an effort from Jorginho in the lead-up.
The result leaves Chelsea second in Group H, level on points with leaders Ajax and third-placed Valenica. The Premier League side go to the Mestalla on matchday five.
It was more of a low key affair at Anfield but Liverpool made hard work of their 2-1 victory over group minnows Genk.
Georginio Wijnaldum’s clever finish gave the Reds an early lead but Mbwana Samatta’s glancing header pegged the European champions back.
Alex Oxlade-Chamberlain restored the home side’s lead and despite a few nervous moments for them, Liverpool just about deserved the three points.
The result and Napoli’s 1-1 draw at home to Red Bull Salzburg leaves Jurgen Klopp’s men top of their group.
Elsewhere, Borussia Dortmund came back from 2-0 down to beat Inter Milan 3-2 in Germany while Barcelona were held to a goalless draw at home to Slavia Prague.
