Jurgen Klopp was pleased with Liverpool’s convincing start to the season, but warned there will be much tougher tests ahead.
The Reds underlined their Premier League title credentials with a comprehensive 4-0 defeat of West Ham in their first game at Anfield.
The German said: “We know about our expectations and we realise there is a really positive atmosphere around us in the pre-season. That is good that people are positive, but this season will be unbelievably hard.
“We cannot be anything different than the challenger because we haven’t won anything since I came in.
“We have to invest more, we have to fight more, we have to create more. That’s the only thing we expect from ourselves. We will see where it leads to.
“West Ham will play, for sure, a good season but they are not the Uniteds, the Citys. We know that and we have to be ready week-in, week-out for all the challenges.”
Liverpool eased to victory with Sadio Mane scoring twice between efforts from Mohamed Salah and substitute Daniel Sturridge.
West Ham offered little as the hosts dominated, but Klopp was reluctant to decribe the performance as perfect.
He said: “It’s a very good start, for sure. It is a start – not perfect but really good.
“Nobody knows exactly how valuable or worthy a pre-season is. You see things in pre-season, but it’s different. The Premier League is a proper fight and you hope, as a manager, your team is ready. You cannot test before you have the test.
“For that it was a clear start, it was good.”
