Liverpool boss Jurgen Klopp insists he's happy with the form of Trent Alexander-Arnold.

For victory over Arsenal, the full-back delivered for Joel Matip's opening goal, and then helped Mo Salah score two.

Klopp said: “Look it's absolutely no problem to be criticised - that's part of the deal.

“We are really clear in what we ask each other for, and yes Trent had to improve - and he did.

“So it's not a criticism in the sense that 'you lost it, you will never be a good defender again', it's just that they all had an exceptional last season, and then had to deal with it in a three week holiday and then they came back and we started new and again."

Klopp continued: “It's not like riding a bike, you lose it - you lose what you had before... as a team.

“It's not like Trent's crosses will not be good. If they are one game, they will be good the next. But as a team you can lose it, defending as a unit and stuff like that.

“You have to come back and start again, and we are doing that, but against Arsenal it was really good, really aggressive."
