Liverpool need improved performance in Porto says Van Dijk

Liverpool defender Virgil Van Dijk insists their Champions League quarter-final is far from won and they will have to be better in Porto next week if they are to progress.

Unlike their last-16 clash just over a year ago, when Jurgen Klopp's side won the first leg in Portugal 5-0 to render the return fixture a formality, a 2-0 victory at Anfield still leaves some work to do.

Van Dijk knows they will have to put in an improved performance next Wednesday as their opponents have shown they can cause them the odd scare.

"Obviously we know it's going to be a tough game and to score two good goals was very important but the clean sheet was the most important thing," said the Holland captain.

"We have something to build on. We kept pressing, we kept going - we played very well I think.

"Obviously in the second half they tried to change it up a little bit: some moments of danger, but I don't think there were any clear chances really.

"But we need to do it a little bit better, especially than in the second half.

"It's a good result and if we score one (away) then it's going to be even more difficult for them to go through.

"But the only thing is that we go in there to play our game, so hopefully we will create chances and finish them off.

"It's going to be tough because their fans are pretty extreme, like here, and I'm definitely going to enjoy that."
