French star Kylian Mbappe is out of Liverpool's price range, the Premier League leaders manager and long-time admirer Jurgen Klopp says.

The 20-year-old Paris Saint Germain striker -- who was instrumental in France's lifting of the 2018 World Cup -- has been linked with Real Madrid.

This gathered momentum earlier in the week when Real's coach Zinedine Zidane remarked that Mbappe had always said it was his dream to play for the Spanish side.

Klopp, speaking ahead of Sunday's clash with second-placed Manchester City, had been keen to sign Mbappe in 2017 and met with the player and his entourage.

However, he opted to join PSG for £158 million ($202 million).

PSG are seeking to extend his present contract and if they were reluctantly to allow him to leave are believed to want more than the record fee of £198 million they paid Barcelona for Neymar in 2017.

"Buying this calibre of player is difficult," Klopp was cited in Saturday's The Times as saying.

"I don't see any club at the moment who can buy Kylian Mbappé from PSG.

"I don't see any club. That is how it is. And we are involved in these clubs who cannot do it. Easy as that."
