Liverpool manager Jurgen Klopp has expressed his delight at his side's performance during their 4-0 drubbing of Barcelona at Wembley this afternoon.

Sadio Mane, Divock Origi and Marko Grujic were all on the scoresheet alongside a Javier Mascherano own goal against his former club as the Reds ran out convincing winners over a Barca side that included the likes of Lionel Messi and Luis Suarez.

Klopp stressed that there was still room for improvement from his side, but was pleased with what he saw in front of a 90,000 crowd at Wembley.

"Of course I'm happy with the result and a lot of parts of the game. Most parts on the tactical side. Always when we were active we were really good and when we were defending, our passing game after winning balls, our direction - great football, good build-up, we played between their rows and in the half-spaces and it was all good," he told the club's official website.

"But we saw then that after 30-something minutes in the first half, we became a little more passive and we needed a bit of luck when they hit the post, and one time Dejan [Lovren] and one time Simon [Mignolet], but that's football and of course that can happen against Barca so that's not a big problem. I could be sitting here today when we had lost 4-0. Life would have not been that nice as it is at the moment, but [it would be] useful too because of the things you can learn.

"But it was Barca, it was a friendly and a lot of things can happen. If they start playing then it's pretty difficult to defend. But of course when you win 4-0 you have to use it. It was wonderful today, special – 90,000 people here for a friendly game and they could enjoy the game. I would say 98% of what happened today was really great."

Liverpool take on Mainz in their final pre-season match on Sunday before beginning the new Premier League campaign away to Arsenal next weekend.
