Arsenal target Vinicius will not return to Real Madrid training this week as doubts over his future rumble on.The Brazil winger was knocked out of the World Cup at the last-16 stage and with new manager Jose Mourinho laying down the foundations for his second spell in charge of the club the expectation in Madrid was that Vinicius’s could return before the end of the month.But the player is staying away while his representatives try to revive talks over an extension to his contract that runs out at the end of this coming season.Madrid’s position is that the player’s future is in his own hands. If he lowers demands to be joint top earner with Kylian Mbappe he will stay.But if he does not the 15-times European Cup winners have no plans to make an improved offer and the way will be left clear for Arsenal. Vinicius Jr has not returned to Real Madrid pre-season training amid his contract stand off New Madrid boss Jose Mourinho had expected the Brazilian to return to training this weekIn a move seen as an illustration of that intention not to fold to the players’ will, Real Madrid moved closer yesterday to making their 100m euros capture of Ivory Coast winger Yan Diomande from RB Leipzig official.The player, represented by the same Roc Nation agency as Vinicius, gives Mourinho yet another attacking option in an already over-populated forward line.The Daily Mail Sport understands Roc Nation’s talks with Real Madrid will centre on Vinicius’s huge commercial worth to the club. The player’s current contract means he gives around 50 per cent of publicity-deal revenue to them, during the World Cup he had lucrative deals with 15 multinational sponsors – a number topped only by his international team-mate Neymar.The 26-year-old has the same representatives as Diomande, who was also on Arsenal’s radar, and there has been interest from Saudi Arabi over the past 12 months.Vinicius is one of a number of forward targets Arsenal are exploring, with Julian Alvarez, Yan Diomande and Bradley Barcola also of interest. Liverpool are considered favourites for Barcola but his situation could change if PSG fail to land Diomande with Madrid leading that charge and trying to close the deal quickly.He is in the final year of his contract and if an agreement cannot be found on a new deal, Madrid could be open to selling, rather than lose him for free next summer.The deal would represent a sensational coup for Arsenal if they were successful but the clubs are still to open official talks.Last year Al Ahli were willing to offer a €1bn five-year contract offer.Liverpool were also credited with interest earlier this window but are not in the mix for a player who earns around £520,000 a week.Vinicius Jnr has scored 128 goals across eight seasons in Madrid, and narrowly missed out on the Ballon d’Or to Rodri in 2024.Daily Mail Sport has reported that Gabriel Martinelli is up for sale as Mikel Arteta looks to add more firepower to his forward line. Leandro Trossard has already been sold to Besiktas, while Arsenal confirmed the signing of Greek winger Christos Tzolis for £34million from Club Bruges on Thursday.
