Liverpool manager Jurgen Klopp believes a 'world class' Harry Kane poses a bigger threat to his side than Manchester United's Romelu Lukaku did last weekend.

The Reds boss succeeded in keeping quiet the in-form Lukaku, who had scored in seven successive Premier League matches before Saturday's goalless draw at Anfield - although the job was made easier by United's tactics and the Belgium striker's reluctance to engage when out of possession.

But Klopp believes Kane, who has 15 goals in 15 appearances for club and country and 81 goals in 102 Premier League matches in the previous three years, is a different prospect.

"I don't have to judge these two. They are both fantastic strikers," he said.

"The difference is that Harry is much more a part of the game when he is not scoring - but I am pretty sure Lukaku can make these steps too.

"We avoided the balls to Lukaku and that must be a key for Harry as well but if we are too concentrated on one player then Dele Alli is everywhere or Eriksen shoots from everywhere with decisive passes.

"It is a good team so you cannot be concentrated on one player.

"It will be a big challenge for them in the next few years because Harry is not only one of the best strikers in Europe, he is one of the best strikers in the world, 100 per cent."
