1. ADRIAN GETS REVENGE OVER ABRAHAM IN THE SHOOT-OUT

Liverpool goalkeeper Adrian was harshly penalized for a supposed foul on Tammy Abraham, with the Chelsea player going to ground despite minimal (if any) contact between the pair as the Blues scored a crucial equalizer from the spot.

But the Reds' stand-in stopper – playing while first-choice keeper Alisson Becker recovers from an ankle injury sustained on the season's opening day – got his revenge when a nervous-looking Abraham stepped up to take Chelsea's crucial fifth penalty in the shoot-out.

Abraham's spot-kick went straight down the middle, and Adrian saved with his trailing leg to win the shoot-out and secure victory for Liverpool.

2. THE ALL-FEMALE OFFICIATING TEAM HAD A BUSY NIGHT

For the first time ever in a major European game, the three on-pitch officials were all women. And the trio of French referee Stephanie Frappert and assistants Manuela Nicolosi of Italy and Michelle O'Neill from the Republic of Ireland had plenty to do on a busy night.

The officials chalked off two Chelsea goals - correctly - for offside, and kept control of the game well. But even though referee Frappert had a strong game in charge, her decision to award a penalty against Adrian for his challenge of Tammy Abraham was proved to be incorrect when viewed on instant replay.

It begged the question: Why didn't VAR overturn the decision when she had clearly made a mistake?

3. N'GOLO KANTE WAS OUT TO IMPRESS

After a season largely spent out of favor under Maurizio Sarri, Kante has been given his place back in the heart of Chelsea's midfield by new boss Frank Lampard. And the Frenchman put in an impressive display, including an outstanding first-half performance that saw him cover an incredible amount of ground in a tireless display.

He even managed to produce a cheeky 'nutmeg' on Liverpool's James Milner, much to the amusement of Chelsea fans online.

4. OLIVIER GIROUD PROVED HE'S A BIG-GAME PLAYER

Left out of Frank Lampard's starting XI against Manchester United at the weekend, French striker Giroud showed his worth in a solid first-half showing that featured a lot of tireless running as he led the line well.

And he capped off a good opening 45 minutes for Chelsea with the first competitive goal of Frank Lampard's Chelsea managerial reign as he slotted a superb Christian Pulisic pass, first-time, past Adrian to put the Blues ahead after 35 minutes.
