Liverpool dominated Villarreal but Klopp's side fully aware Champions League comebacks can happen

LIVERPOOL, England -- Don't be fooled by the narrow margin of the scoreline.

Liverpool's 2-0 victory over Villarreal at Anfield was the most one-sided semifinal you are likely to see and could and should have been so much more for the six-time European champions.

But 2-0 might well be more than enough to keep alive Liverpool's dream of winning four major trophies in one season.

Unai Emery's team still has 90 minutes in next Tuesday's second leg to salvage this tie

and reach the Champions League final in Paris on May 28,

but it would go against all logic and statistical evidence to believe that Liverpool will succumb to what seems an unthinkable Villarreal fightback.

"It's 2-0 at half-time [in the tie]," Jurgen Klopp said. "This is the best example of a score when you have to be completely on alert.

We will have to be 100 percent in the right mood and play the second leg in exactly the same way we played the first. The score is fine, but we are not through."

That they won only 2-0 was down to missed chances as well as Villarreal's organisation and defensive discipline.
