Liverpool manager Jurgen Klopp has criticised his players after a miserable display against Manchester City.
The Reds boss was furious at the way his team capitulated during a 4-1 loss to last season's Premier League champions.
Klopp told his players that football has not turned into rocket science overnight," suggesting they are not doing the basics properly.
Speaking to reporters, he stated: It's about basics. It is not rocket science or has not turned into rocket science overnight. Yes. Yes, it is right. Football is based on basics, definitely, and yes I was not happy with it but I said that directly after the (City) game.
We did not tackle (against City). First goal, a pass to the outside and no challenge. The third goal is four or five versus one and then a pass arrives still in the box. That is not possible. We have to make sure we have a completely different approach to challenges, that is 100 per cent true."
