Real Madrid superstar Vinicius Junior is reported to have shown interest in the proposals from the Saudi Pro League that could make him the highest paid footballer in history.There has been interest in Vinicius from Saudi Arabia for over a year and the numbers being talked about are on another level, even for the oil-rich Gulf nation.A potential transfer fee could reach a world record €300m, with Vinicius able to earn an eye-watering €1bn over the course of a five-year contract.MARCA has reported that Vinicius first met with Saudi officials on a video call in 2023, described as a relaxed chat which lasted only around 15 minutes. In addition to the money on offer, it was put to the player that he could be an ambassador for the 2034 World Cup.A more formal second meeting is said to have later been held face to face in Prague, of all places, away from the media spotlight and in neutral territory. That is when the exorbitant figures involved are claimed to have been agreed on.
