It's probably an understatement to say Liverpool endured a miserable afternon at Wembley on Sunday.The Reds will take no comfort in the fact that they had over 60% of the possession because, of course, the only stat that matters is that Tottenham scored four, and the visitors got one.Goals from Harry Kane and Heung-Min Son put Mauricio Pochettino's side two up within the first 12 minutes.A scrappy Mohamed Salah goal followed, but any hopes of a comeback were dashed when Dele Alli capitalised on some awful defending just before half-time to add Spurs' third of the afternoon.Joel Matip was at fault on that occasion, while Dejan Lovren had already been taken off. Jurgen Klopp confirmed in his press conference that the Croat wasn't injured, making it all the more embarrassing that he was removed from the action within the first half hour.The narrative of Liverpool's atrocious displays at the back has been done to death already this season.However, there's a good reason people keep talking about it. They've now conceded more away goals than any other Premier League side this term, shipping four against Spurs and five against Manchester City.Paralympian Ali Jawad, who happens to support Liverpool, took the opportunity to have a dig at his team over their latest performance - and it's easy to see why his tweet has gone viral:

It's no laughing matter for Klopp, though, who is now under genuine pressure with his side ninth in the table.

As loveable as the German is, he has to bear some responsibility for failing to find an alternative when Southampton refused to sell Virgil van Dijk in the summer.

The same old problems

Then there's the small matter of why Alberto Moreno is still starting at left-back.

Some fans were also keen to point out that Lovren actually excelled under Pochettino when the pair worked together at St Mary's, so perhaps it's not out of line to speculate that all isn't well on the training ground either.

Their next game ought to give them some respite as they welcome Huddersfield to Anfield, but the Terriers proved at the weekend that they're no pushovers with a shock win over Manchester United.

At this rate, it's going to be a long, long season on Merseyside.

Is Klopp to blame for Liverpool's defensive problems? Have your say in the comments.
