Mourinho's first task at Real Madrid is to build the defense, targeting a Premier League champion left-back.

Florentino Pérez is almost certain to be re-elected as Real Madrid's president, and a leaked video of Mourinho in a Real Madrid shirt suggests he is likely the next head coach. As a proven winner, Mourinho prioritizes defense. Real Madrid may have already secured two defenders: Liverpool's starting center-back Ibrahima Konaté (free transfer) and Inter Milan's right-back Denzel Dumfries (€20 million release clause). Mourinho also wants to bolster the attack by signing a strong left-back, and has set his sights on Arsenal's Premier League-winning left-back Riccardo Calafiori.

According to renowned journalist Fabrizio Romano, Real Madrid are looking for a left-back who can also play center-back. They have already contacted Italian defender Riccardo Calafiori. While the club also admires Manchester City's Joško Gvardiol, signing him would be extremely difficult given City paid €90 million for him and he is a key starter. Therefore, Real Madrid believe targeting Calafiori is a more realistic move.

Calafiori, a 27-year-old Italian international standing 1.88m tall, is valued at €55 million by Transfermarkt. Capable of playing both left-back and center-back, he fits Mourinho's tactical requirements perfectly.

In my opinion, Calafiori might struggle a bit in the Premier League due to his lack of pace, but he would perform well in La Liga. His versatility as both a left-back and center-back would appeal to Mourinho. As long as Real Madrid make a reasonable offer, Arsenal would be willing to sell him.

Calafiori's stats for Arsenal last season: 36 appearances in all competitions, 28 of which were starts, totaling 2,261 minutes on the pitch, with 1 goal and 3 assists.
