Barcelona hero Patrick Kluivert is full of praise for Liverpool boss Jurgen Klopp.

Klopp's Liverpool will face Barca tomorrow night in the first-leg of their Champions League semifinal tie.

“It is important for a football player to have someone who believes in you. It ensures that you take an extra step for the trainer and that is what is going on at Liverpool," said Kluivert.

"And also at Tottenham Hotspur with Mauricio Pochettino. The Premier League can be happy with those two and also with Josep Guardiola at Manchester City."

On whether Liverpool can win at the Nou Camp, the Dutchman added: "The Champions League has become an important prize for Barcelona after the success of Real Madrid. But Liverpool will be the toughest opponent they have faced so far and they have no guarantee that they will continue and win the tournament."
