Reporter： Real Madrid’s number one goal in 2024 is Mbappé, and the team is waiting for his contract to expire.

Live on May 20th, recently, the Spanish website remontadablanca interviewed Carlos Carpio, deputy editor-in-chief of Marca. In this conversation, the latter said that the number one target of Real Madrid next season is Mbappé, and the possibility of players transferring this summer is almost zero.

The website wrote: "Mbappé will be the number one target of Real Madrid next season. In fact, according to Carlos Carpio, Mbappé’s team is still in regular contact with Real Madrid. However, the possibility of his transfer in the summer window of 2023 has almost been ruled out. “

"Real Madrid executives are not considering taking any action for Mbappé this season. Besides, they don’t think Paris will agree to sell Mbappé, so they have to wait until Mbappé’s contract expires soon. “

Mbappé renewed his contract with Paris in May, 2022. Earlier, L ‘Equipe and Marca reported that his renewal period with Paris was 2+1. In the third year, he had the right to decide whether to renew his contract for one year, so now Mbappé’s contract will expire on June 30, 2024, which allows him to start negotiations with other clubs in early 2024.

Regarding the transfer of Bellingham, the reporter said that the players are very eager to play in Real Madrid. At the same time, Real Madrid executives have told modric that Bellingham will join next season, so Magic Flute should realize that his playing time may be gradually reduced.

I started as James, who played as a center： I was almost eliminated by Chelsea Youth Academy that year.

Chelsea defender Reese James said in an interview that he was almost eliminated by Chelsea youth training in the past and revealed that he started as a striker.

James said: "I signed for Chelsea when I was about eight or nine years old. I stood out among my peers. We have Du Qiong Sterling, martel Croasdale, Ryan Brewster, Jamie Cumming, Mark Gay and Connor Gallagher, and several of us have succeeded."

"All of us dream of playing for Chelsea, but when we were growing up, people knew it was difficult to get into the first team because not many people could do it in recent years. We knew what we wanted, but it was difficult to achieve at that time. "

"But when Lampard was the head coach, he really helped the youth training and the first team to cooperate better. Even now that he has left, the youth training and the first team still maintain his legacy, as evidenced by the addition of some young players last season. They got the opportunity and completed their first show, which is both recognition for the players and affirmation for the staff. "

"When I was growing up, I was a striker. I admired Drogba and I always admired him. I just want to score goals and celebrate like him. I stopped playing as a striker at the age of eleven or twelve and started to develop in the midfield. I stayed there for three or four years, and then I found myself suitable to play as a right-back at the age of fifteen. I hated this position at first. Until one day, I suddenly felt adapted to this position and began to really enjoy it, about seventeen years old. But it really takes me a long time to get used to this position. When I don’t want to play this position, this position often makes me feel depressed.

"But right-back is the position where I play the most now, and it is also my favorite position. I have hardly played in other positions. I have been there since I joined Chelsea, but when I was fifteen or sixteen, I was almost eliminated. I am probably one of the worst players in that age group, and they are not sure how I will develop. When they offered me a new contract, they took great risks. I must try my best to prove that I can play football and achieve my goals. "
