After France's victory over Morocco in the World Cup quarter-finals with two unanswered goals, Jurgen Klopp was one of the most notable sights on the pitch of Foxborough Stadium.

Klopp currently works as an analyst for Magenta TV, and when he finished the coverage, he stopped to warmly and friendly greet Mbappe, which the French star reciprocated.

According to AS newspaper, Klopp recounted how he tried to convince Mbappe to move to Liverpool on a private plane that took off specifically for this mission, and he joked, 'It was the most expensive deal that never happened in my life.'

The story dates back to 2017, when Mbappe was preparing to leave Monaco in search of a big club, and Liverpool was determined to compete strongly to sign him, so his then-manager Klopp was sent to try to persuade the player.

The operation was carried out in complete secrecy: a private plane took off from Blackpool to Nice, two cities far from the media spotlight, where Kylian, still a minor at the time, was waiting with all his family members.

Klopp revealed that the meeting was not held in a quiet place on the ground as some might expect, but entirely while flying.

Klopp said, 'We were flying in circles above the clouds and had a delicious meal. We couldn't allow anyone to see us.'

In the end, Mbappe did not choose Liverpool, but preferred to move to Paris Saint-Germain.

Klopp concluded his story without any bitterness, saying, 'It was fantastic, but he ended up in Paris.'
