Sadio Mane gave Liverpool the lead in Munich. Liverpool, along with Tottenham, Manchester United and Manchester City, will all compete in the last eight of the competition -- coincidentally four teams whose cities all voted to remain in the 2016 Brexit referendum.

We don't know who we are going to get in the next round but we have good feelings from last year so hopefully we can carry that on and go as far as we can." While British lawmakers will now vote on Thursday to decide whether Brexit should be postponed beyond the deadline, Liverpool ensured its own participation in European competition will continue into April. After a goalless first leg at Anfield three weeks ago, may neutral observers had hoped for a more exciting contest this time around. Instead, what was served up was a rather dour affair, littered with errors from both sides and an inability to keep possession. Liverpool, last year's beaten finalist, always carried the greater threat going forward with Sadio Mane, the man in form, a constant thorn in Bayern's side. Is VAR 'killing' football? It was Mane who missed a number of chances in the first game, but on this occasion, the forward did not disappoint, displaying sublime skill to control Virgil van Dijk's long ball before coolly curling the ball into the far corner. Bayern, who had not even mustered a single shot at goal in the first leg, moved level in fortunate circumstances six minutes before the break when Joel Matip inadvertently diverted the ball into his own net.

"I didn't just want to beat Bayern, I wanted to win with Liverpool," Klopp told BT Sport. "I am sure I will have a lot of fans happy from Dortmund and if I can help them, then that's great too. "It is a wonderful Champions League night for Liverpool again and that's good."
