Vinícius Júnior has returned to Real Madrid training after representing Brazil at the World Cup, amid ongoing transfer speculation linking him with Arsenal.

The Brazilian winger underwent medical checks at the Blua Sanitas Valdebebas Hospital before joining his teammates for the first session under new coach José Mourinho.

ESPN reported that Real Madrid are willing to let Vinícius leave this summer if he doesn't sign a new contract, with just one year remaining on his current deal.

While Arsenal believe they are in a strong position to sign the forward, manager Mikel Arteta declined to comment on the potential move when speaking to the media. No date has been set for contract negotiations between Madrid and the player's representatives.

Madrid drew 2-2 with Fiorentina in their opening pre-season friendly, with Vinícius' Brazil teammate Endrick scoring for the home side.
