Real Madrid signing Eder Militao suffered a dizzy spell after his official presentation as a new player for the Spanish giants.
Militao had to cut short his debut media conference at Santiago Bernabeu on Wednesday when he said he was feeling faint.
The 21-year-old centre-back loosened his tie, bowed his head and took a long drink of water before asking to leave.
The Spanish club has not commented on his condition, which appeared to be temporary.
The former FC Porto player had undergone a medical check-up just hours before he had his spell.
Militao had earlier said of his move: "It’s a huge emotional moment and a very special day for me and my family.
"We have reached a very high level and the best club in the world.
"It’s a very special day and I’m very happy to have arrived at Real Madrid."
Militao is joining Madrid after helping Brazil win the Copa America.
Madrid signed him in March from Portuguese club Porto, where he continued to play for the rest of last season.
He is now under contract with Zinedine Zidane's team through 2025.
