Liverpool manager Jurgen Klopp has insisted that his side must continue to improve despite their 3-0 victory over Bayern Munich at the Allianz Arena on Tuesday.

Goals from Sadio Mane, Mohamed Salah and Daniel Sturridge saw the Reds sweep the German champions aside to reach the final of the Audi Cup, extending their unbeaten pre-season run in the process.

The pace of Mane and Salah in particular caused Bayern all sorts of problems, but Klopp refused to wax lyrical about his side's performance and instead pointed out the areas that still need improvement.

"Sadio is not where he can be so he needs playing time, playing time, playing time. We won 3-0 but I don't like running around saying: 'How good was this?' because it wasn't. In a few parts of course it was good, in a few other parts everyone saw that Bayern had the ball too often and it was too easy to play through our lines. I cannot ignore this," he told reporters.

"Of course [Mane and Salah] are both good but they don't need to know it all the time when they play together, with Phil Coutinho behind as well to play all the passes for them to run in behind. Football is not that easy so I don't want to talk about this. Yes it looks good but they need to get fit and stay fit and hard and resistant because the season will be difficult. That is what we are preparing. I have to speak about things that are not good because I see it.

"The beginning of the second half showed that in a game like this – and OK, 2-0 at half-time is a good result – we can be dominant with the ball against an opponent like Bayern. In that case we should do it, not wait until the second half or whatever. It is not that I am trying to make the league afraid and think: 'Oh my God, Liverpool beat Bayern 3-0 and they can do better.' No. We have to do better and that is what we are working on."

Liverpool will face Atletico Madrid in the final of the Audi Cup this evening.
