Liverpool’s Jordan Henderson has expressed some anxiety ahead of their second leg game against Villareal.
They are two goals ahead, as they recorded home on Wednesday but he concedes the battle is not yet over.
“They are a very organised team and we knew they would make it difficult.
“It was just important that we kept going and believed that we would eventually break them down. We did that with two good goals,” Henderson said.
But he warned that “the game is still alive and it will be tough in Villarreal.”
Pervis Estupinan deflected team captain Jordan Henderson’s cross into his own net in the 53rd minute and Sadio Mane got the second two minutes later.
The result left the six-time winners well-placed for the return leg in Spain on Tuesday.
Villarreal, who had stunned Juventus and Bayern Munich in the previous rounds, had frustrated Liverpool in the first half before being well beaten.
They created no serious scoring opportunity with just one attempt, compared to Liverpool’s 20.
Jürgen Klopp’s Reds have already won the League Cup, are in the FA Cup final against Chelsea and trail Manchester City by one point in a fierce Premier League title duel.
Should they reach the Champions League final on May 28 in Paris, Pep Guardiola’s Manchester City could also be their opponents there.
This was after Manchester City beat Real Madrid 4-3 in a thrilling other first-leg semi-final on Tuesday.
