Liverpool travel to Spain to take on Villarreal in the first leg of their Europa League semi-final on Thursday.
With Villarreal currently fourth in La Liga, the trip to El Madrigal looks a daunting one for Jurgen Klopp's side. But what can the Reds expect from their opponents?
Sky Sports' La Liga expert Terry Gibson gives us his verdict…
What's their style of play?
"They're not a team that scores a lot of goals," Gibson told Sky Sports. "When they played Real Sociedad at the weekend, both teams have scored 42 goals this season. The difference is that Villarreal have conceded far fewer goals. That's been their strength."
In fact, Villarreal have the third best defence in La Liga with only the top two of Barcelona and Atletico Madrid bettering their efforts. "At times, we've been able to compare them to Atletico in terms of their style of play," added Gibson. "They're a lighter version of that.
"They keep it tight in a 4-4-2. Don't expect them to open up and try to blow Liverpool away in 20 minutes. That's not their style. They're slow burners. They'll tick over, ease themselves into a game through possession and rely on Cedric Bakambu to break down their defence."
Is Bakambu the key man?
The summer signing from Bursaspor has certainly made an impression in his first season with the club, scoring 12 goals in La Liga - more than twice as many as any other Villarreal player. But Gibson feels Bakambu needs more support from strike partner Roberto Soldado.
"Bakambu looks lively which is proving a saviour for them at the moment," he says. "Soldado isn't scoring. We keep saying that he's creating and contributing to the partnership but he has to start scoring goals. He has to deliver against Liverpool over the two legs."
So are they in form?
"I'm concerned about their upcoming fixture against Liverpool," adds Gibson. "I think they are running out of steam. There have been a couple of defeats prior to the game against Real Sociedad - and they weren't great against Real Sociedad."
Villarreal have had several good runs of form in La Liga, winning five in a row early in the campaign and then repeating that trick either side of Christmas. But Marcelino's men go into this tie having won only two of their last eight league games.
"It's an interesting one to call because they've had that cushion between fourth and fifth and the teams below haven't really put on the pressure," says Gibson. "They haven't really had to stretch themselves in La Liga. Can they turn the form back on? It'll be interesting."
Who are the favourites?
"I would probably put Liverpool as favourites, particularly with the second leg at Anfield," adds Gibson. "But I'm a little unsure because I want to wait and see whether Villarreal could suddenly kick back into life and be the team they were six weeks ago.
"We know the importance of European football to a club like Villarreal as it's a relatively small club despite their success over the past decade or so. Prior to that, there wasn't much history so a European semi-final against a legendary club like Liverpool is a huge occasion."
