Five things learned about Liverpool in first leg defeat to Villarreal

Liverpool Wall

Liverpool lost the first leg of their Europa League semi-final 1-0 against Villarreal at El Madrigal.

There will naturally be some disappointment among the Liverpool players after their last minute 1-0 defeat to Villarreal in the first leg of their Europa League semi-final at El Madrigal.

Adrian Lopez tapped home in stoppage time to give the Yellow Submarine a narrow advantage ahead of the second leg at Anfield next week when it seemed as if the first leg was going to end in a goalless draw.

Both sides had their chances in a cagey encounter. Joe Allen and Roberto Firmino had the Reds' best chances and Cedric Bakambu was denied by the outside of the post - as well as a fine save from Simon Mignolet.

Liverpool seemed pretty content with their work up until the final stages, and only the outcome from the second leg will inform us as to how costly that late lapse was during last night's encounter. 

Here are five things we may have learned:

Even in disciplined performances, still some players are prone to switching off

For 85 minutes of this encounter, Liverpool's defensive display was near faultless. Kolo Toure looked excellent at the back alongside Dejan Lovren, and chances were few and far between for the home side, but in the latter stages it all got a bit chaotic. 

Ibe's lapse in concentration led to a brilliant chance for Bakambu, fingers have been pointed at Moreno for the goal - who didn't enjoy the best of nights as there were one or two occasions when they threaded passes inside him a little too much. The executions from individuals on the pitch was the fine line between this performance being dubbed a tactical masterclass, to questions being asked of the manager's approach.

Injuries and suspensions have taken their toll as some players really started to tire

This isn't knocking those that replaced Emre Can, Jordan Henderson and Mamadou Sakho in particular. Kolo Toure was excellent for the large part of the game - and bailed his defence out on a couple of occasions - while Joe Allen and Lucas Leiva also performed well. But you couldn't help but feel that a lack of match practice was a factor later on in the game when Villarreal were starting to get a bit more joy. 

The thinking about Sturridge will have to be reserved for the second leg

Questions are being asked about Daniel Sturridge being an unused substitute. Personally, I would've introduced him at the hour mark, but I'm not the Liverpool manager - and I'm sure he's better at this than me. But it's hard to think that he won't be on from the start of the second leg on Thursday, especially given the scoreline. If he's fresh, scores a hat-trick, and Liverpool progress to the final, you could then argue he's right to have left him out last night. 

Klopp likely to be bold in a different sense in second leg 

His post-match comments were a bit of a giveaway, with the Liverpool manager saying that it's not over and suggestions they'll throw the kitchen sink at their opponents. 

Klopp lined up in the first leg of the Borussia Dortmund tie very much in the same way as he did last night - with a midfield three - and it wouldn't be a surprise if one of them takes up a more advanced role in the second leg.

Divock Origi's absence felt 

It's hard to think the Belgian wouldn't be leading the line instead of Roberto Firmino if he was fit. Liverpool lacked a bit of presence up front, and off the ball he would've done the job just as well as Brazilian. Not just that, he would've provided more of a goal threat, and it seems that other members of the side wanted someone to head in a cross.
