Liverpool boss Jurgen Klopp has refused to enter a war of words with Manchester United rival Jose Mourinho.

Mourinho has tried to kick off the mind games by suggesting that both Liverpool and champions Chelsea would find things more difficult this season as they would have to deal with European football.

"I'm not interested in what Jose Mourinho says," Klopp responded.

"Why should I talk about Manchester United? Jose is talking about us, yes. We had a season of what Man United had the year before. I don't know if anybody asked us how it felt (then)."

The Liverpool manager even suggested his Old Trafford counterpart may be right.

"The Europa League was hard,' he said. 'Yes, Chelsea will feel also the difference, they played something like 13 players last season. But it's also not my problem if they use only 11, well done. I do not want to be part of this – I am not interested."
