Liverpool made it through to the Carabao Cup quarterfinals in dramatic fashion on Wednesday night as they beat Chelsea 6-5 on penalties after a 1-1 draw.
Giorgi Mamardashvili was the hero as he kept out Chelsea debutant Emmanuel Emegha's spot kick to deny the visitors victory, before Wesley Fofana shot over the bar to end the shootout.

Liverpool have now won five games in a row, and key to their upturn in form has been the performances of some of their big-money signings.
Alexander Isak has scored six goals in seven Premier League games, Bradley Barcola has five goal involvements in his last three starts and Florian Wirtz scored the decisive goal in the Reds' 4-3 victory over Villarreal last week.
The German was forced off during Liverpool's 2-0 win over Brighton and Hove Albion at the weekend, but Iraola said on Tuesday that he was optimistic that Wirtz would be available for the game against Chelsea.
"We still have to wait," Iraola said in his prematch news conference. "We train later. We want to [use] this last day. He was quite fine, Florian -- I'm quite optimistic that he will be available.
"And with Dom[inik Szoboszlai] and Victor [Muñoz], I'm not so sure. I don't want to say no, but I think it's going to be more difficult than Florian, yes."
Wirtz later came on as a second-half substitute.
Chelsea, meanwhile, were unable to bounce back from defeat to Spurs, having had to do so without Cole Palmer and João Pedro.
The former was suspended after being sent off on Saturday while the latter will be out for weeks with a thigh injury.
