Jürgen Klopp has explained how Liverpool’s revised work on set-pieces in training is behind their enhanced threat from dead-ball situations this season.

In Premier League terms, the Reds have netted five goals so far this term following either corner kick or free-kick routines.

And Klopp has detailed why it’s an area he and his backroom team were keen to improve, beginning from when the players returned to training in the summer.

Asked how much work Liverpool have put into set-piece situations, Klopp told his pre-match press conference on Friday: “A lot, a lot. We did a lot on set-pieces.

“Actually, it’s quite difficult to talk about set-pieces because you don’t want to talk about it! [For] the routines, there are different runs and different things.

“We did it in pre-season – and it was clear at the start of pre-season that we want to focus on it because it was not a proper strength of ours. That’s what we do week in and week out. It doesn’t work out all the time, but I would say it is a different approach that we choose. We have different runs, never the same routine, so it’s always something different. We put more focus on it.

“[Sometimes] you really cut off really important training time for set-pieces – and for set-piece training in England, it is quite difficult because it’s not very lively. I haven’t spoken for a while about the weather because it was so good, but it’s rather cold [here] and in Germany it is similar.

“In Spain you could work five hours a week on set-pieces, that’s not a problem – but because of the weather in England and Germany it is quite difficult because when it is cold you cannot stand around. It’s never very lively, ‘you go there, you go there, you run there, you block here…’ and at the end everybody is so cold!

“We did a lot and it’s good to see that it worked out somehow.”
