So that's that then.
The Man City League Cup stranglehold is over. West Ham have seen them off on pens.
They are one of five London clubs in the last eight. Leicester, Liverpool and Sunderland the three clubs not from the capital who are still in with a shout.
Join us this weekend as we return to Premier League action. Night all.
Preston 0-2 Liverpool
Liverpool
Liverpool defender Neco Williams speaking to Sky Sports: "Preston are a good side, they gave us a good game. We didn't play our best football but we did enough to get the win and we're happy with that. The team put a shift in, we worked them."
On his goal-line clearance: "It smashed me in the mouth and I didn't remember much. I was there on the line and I thought I'd have a good chance of blocking it. Luckily it's smashed me in the face and stopped a goal."
On his own performance: "I tried to play as high as I can. I should have got on the scoresheet but nevermind, hopefully next game I score. I think I did well, I gave everything I had. I got a bit of cramp towards the end but I think that's just down to hard work."

The draw for the quarter-finals is not taking place tonight.
It's actually happening on Saturday at 10:30 BST.
So if you're sticking around for that, don't.
And for the first time since the 2016-17 season, someone other than Manchester City will be lifting aloft the League Cup at Wembley.
So that is our quarter-final line-up complete. Arsenal, Chelsea and Sunderland are joined by Tottenham, Leicester, Liverpool, Brentford and West Ham.
