"Neil Lennon, asked what he didn't like about referee Roger East's performance: "I thought he was rubbish." There you go...."
BBC Radio 5 live's Kevin Kilbane
"By playing Emre Can in the back three, Steven Gerrard has the confidence to go forward as he knows that Can is confident on the ball."
There are 10 Premier League sides still in the FA Cup, with Bradford City of League One the lowest-ranked side still in.
We are guaranteed at least one Championship side in the last eight as Derby face Reading.
Yakubu to win it?
Bolton boss Neil Lennon: "I'm not happy with the referee tonight at all. Neil Danns' first yellow card was not a booking and I'm not convinced that our penalty was a penalty either.
"This is a step up in class and you have to concentrate for 96 minutes. They scored two good goals but they could have been avoided. We were foot perfect for nearly 180 minutes in defence but it wasn't quite enough.
"The game's gone now but hopefully we can learn from that."
Derby, Fulham, Watford, Nottingham Forest, Middlesbrough, Brighton. Bolton's February list of fixtures is no easier.
The Trotters are 13 points off the play-offs and seven points above the relegation zone.
Former Liverpool striker John Aldridge: Emre Can gets better every time I see him. Could be a big player in the future for us. Proper football brain too! Philippe Coutinho deserved that goal!
Liverpool manager Brendan Rodgers on BBC One: "It was always going to be a tough game. Neil Lennon's done a brilliant job at Bolton. Going 1-0 behind away from home put us on the back foot. I think you can see on the replay it was nowhere near a penalty. We must have hit the bar about five or six times but eventually the quality came through.
"You have to keep your patience and keep the width in the game, especially against 10 men. It was a great pass by Emre Can for the first goal and a great finish, and a wonderful finish for the second goal [from Philippe Coutinho].
"This is a competition we want to do well in and thankfully we're into the next round against Crystal Palace."
Everton, Spurs, Crystal Palace, Besiktas, Southampton, Besiktas.
That's the rest of Liverpool's February schedule as they still fight on three fronts.

Liverpool forward Raheem Sterling talking on BBC Radio 5 live: "We had a few chances to score. When we kept hitting the woodwork I wondered if it was perhaps not our day, but we stuck in there and Philippe's winner was brilliant. He's just a magician."

Kevin Chadwick: You have to start putting Philippe Coutinho in the same bracket as David Silva. Another magician with the ball.
Tim Mann: Great cup tie from Liverpool and Bolton! Shows the FA Cup IS the greatest competition in the world, just keeps on giving!
Shaun Howe: As a Liverpool fan I can tell you that we are going to win like this all the way through the tournament. Never a dull moment!

"The sending off of Neil Danns didn't help Bolton. Ultimately the quality of Liverpool shone through, but they rode their luck a bit."
Liverpool have reached the FA Cup fifth round in successive seasons for the first time since 1995 and 1996. Manchester United and Eric Cantona beat Liverpool in the final in 1996 - the cream suits year.
BBC Radio 5 live's Kevin Kilbane
"It's been a super game. Brilliant to watch. Bolton scored from a very debatable penalty but after the sending off, Liverpool really turned it on. The game was end to end. Great cup tie."
Liverpool forward Raheem Sterling on BBC One: "We had a few chances to put the game away but we didn't take it. It was a great team effort to stick in the game and get the win in the end.
"When we went 1-0 down and hit the post three times it didn't look like our day but we got there in the end. Philippe Coutinho has the magic to turn the game on its head and we saw that again."
The Bolton fans cheer their fans off the pitch. The Championship side put in a right shift but that needless red card has cost them in the last few minutes. Would they have won with 11 men? We'll never know.
Liverpool will play Crystal Palace in the fifth round after a late, late show. Bolton were five minutes away from a famous win.
BBC Radio 5 live's Kevin Kilbane
"It's been a great cup tie. It looked like it was going to extra time. There's been everything. Controversy, a red card and great goals."
