Kylian Mbappe is already a superstar in the French national team and the PSG. Before transferring to Paris, the young striker was compared to Thierry Henry. Now, Mbappe is seen as a true candidate for the Golden Bubble. As I already informed HERE a couple of months ago, the Frenchman could have signed with Chelsea at the age of 13, but the Premier League team wasted the chance.Serge Daniel Boga, Chelsea scouter, told the English press exactly how things happened at the time. Initially, the Premier League club called the French in a probation period of 6 months. Although Mbappe impressed with his offensive qualities, Abramovich's club refused to pay the £ 14,000 ridiculous sum for the forward transfer. Instead of the young footballer, London officials preferred Tammy Abraham and Dominic Solanke. After the first probation period, Chelsea called Mbappe once more for six months, but the footballer's mother opposed: "Listen, my boy will not come back here. If they want it, he has to take it now or in 5 years will take it in exchange for 50 million euros, "said Mbappe's mother.The Scouter who has set his eyes on the talented Frenchman has revealed why Chelsea has not signed with Mbappe. In his opinion, the striker did not meet the defensive expectations: "He was very technical, but in England he wants the player to repel and to be a worker. When he had the ball, it was incredible, but when he did not he had a ball in his leg, he did not work very well. He had very good technical skills, excellent dribble, so I think Chelsea probably wanted to see the progress on the defensive in the second probation period, "Boga revealed.Serge Boga regrets that Chelsea officials did not sign Mbappe: "I think Mbappe is the best player I've ever found," said the scooter.At just 19, Mbappe has some incredible figures. At his age, Cristiano Ronaldo and Lionel Messi did not seem to be as promising players as the Frenchman. See HERE the numbers of the 3 players up to the age of 19 in professional football.
