Liverpool smell a third Champions League final in five seasons with dominant win over Villarreal

LIVERPOOL: Jurgen Klopp said Liverpool have to remain "on alert" despite putting one foot in the Champions League final with a dominant 2-0 win over Villarreal in the the first leg of their semifinal tie at Anfield on Wednesday.

Two goals in two minutes undid Villarreal boss Unai Emery's defensive game plan as Pervis Estupinan deflected Jordan Henderson's cross into his own net before Sadio Mane slotted in a second.

"It is 2-0 at halftime," said Klopp. "You have to be completely on alert, 100 percent in the right moment and play the second half like we played the first. We know it will be a tricky atmopshere for us."

However, the Yellow Submarine could barely lay a glove on Klopp's men as Liverpool just had to bide their time to make their dominance count.

"The 2-0 is a clear, deserved result," said Emery. "It could have been even worse but we still have a chance.

Mane headed wide Mohamed Salah's pinpoint cross with the best opening.

The Senegalese also saw a deflected effort fly just wide and
