Liverpool boss, Jurgen Klopp has revealed how he managed to turn things around at Villarreal during their Champions League quarter-final second leg on Tuesday.

The German admitted that the half-time introduction of £37.5m January signing, Luis Diaz, reinvigorated his side and changed the game.

Liverpool also benefited immensely from a poor goalkeeping performance from the hosts’ Geronimo Rulli.

Both Fabinho and Diaz’s goals went through the goalkeeper’s legs, while he was also beaten to the ball by Sadio Mane when he came charging out, to leave the Senegalese forward with an unguarded net to seal the win on the night.

Now the Reds are crossing their legs, waiting for the winner of the second semi-final tie between Manchester City and Real Madrid at the Santiago Bernabeu on Wednesday.

Pep Guardiola’s City have a narrow advantage over Carlo Ancelotti’s side, having won the first leg 4-3 in England.

“We knew what was wrong because it was obvious, but we didn’t have a situation to show them where we got it right,” Klopp told BT Sport.

“I said [to my staff] ‘find one where we do it well and we can show it’, and we came in and they said ‘no, we don’t have it’.

Obviously Luis, what a player he is, but it’s not about who came on, it was about how we started to play.”
