Sources indicate that Real Madrid`s star player, Kylian Mbappe, lost as much as five kilograms after being unwell in the past week.

After being discharged and returning to the team hotel, he had to stay isolated from his teammates to prevent spreading the illness.
Mbappe began training individually on Monday and is aiming to rejoin the rest of the squad soon.
The illness, however, has significantly impacted the French player.
According to the Spanish publication Marca, the virus caused him to lose between four and five kilograms.
This weight loss has led to fans expressing worry, with comments on social media like: “He really needs to rest.”
Another fan commented: “It`s clear, he needs time to fully recover.”
It is thought the virus might have been contracted in Madrid before the team flew to the US earlier this month.
He started feeling sick after the team`s second training session held in Miami.
Mbappe is hopeful of being fit to play in Real Madrid`s last group stage match against RB Salzburg, scheduled for Thursday.
Real Madrid currently leads Group H with four points after playing two games.
They drew 1-1 with Al-Hilal in their first match and then defeated Mexican team Pachuca 3-1 on Sunday.
Mbappe did not participate in either of these games.
Over the weekend, Real Madrid`s new manager, Xabi Alonso, commented on the forward`s situation, stating: “I look forward to his return, but we need to monitor his progress daily.”
Alonso added: “We must wait. We are now returning to Florida and will assess his condition. We are waiting for him.”
