Manchester United and Chelsea are stepping up their pursuit of Real Madrid's rising star

For Real Madrid, one of the revelations of the pre-season so far has been Joan Martinez. The 16-year-old centre-back has been with Carlo Ancelotti's side for the past few weeks, and earlier this week, he impressed on his first-team debut against AC Milan.

Due to Ancelotti's lack of options in central defense due to the departures of Nacho Fernandez and Rafa Marin, Martinez is likely to remain in the first team dynamic at Real Madrid. However, a number of clubs in the Premier League hope that this is not the case, as they plan to sign him this summer.

According to AS Diary, Manchester United and Chelsea are two of the teams that are interested in Martinez. However, Real Madrid is relaxed about the situation, because they believe that the teenager has no desire to leave.

Martinez could become an important player for Real Madrid in the coming years, to the point that the owners of the club forget everything about Leny Yoro, who did not sign before the summer. It already is he has been compared to legendary defender Sergio Ramos.
