"In addition to great players, they are very good friends".
However, there are unlikely to be any developments until Brazil's participation in the World Cup is over.
Willian and Martial have been linked with moves away from their respective clubs and the Telegraph claims that we still have a chance if we throw the 22-year-old Martial into the deal, despite Barcelona being interested in the Brazilian winger.
Mina, though, maintains that he doesn't want to leave Camp Nou having only joined from Palmeiras in January and his uncle, who is also his agent, says there are no offers for the Colombia World Cup star.
The Europeans may be star-studded but the five-time winners are the favourites to reach the last four in Russian Federation.
"Those two are brilliant and how Willian didn't play more games is beyond me". The Blues want £70 million for Willian after the Catalan outfit bid £50m for the former Shakhtar Donetsk star but the La Liga and Copa del Rey Champions are also hopeful that Willian will personally push for a move away from the Emirate FA Cup victor.
Brazil's exit from the tournament after a 2-1 defeat to Belgium in the quarter-finals means Willian can now turn his attentions to his club future. However, Real Madrid midfielder Casemiro will miss the match due to suspension, with Fernandinho expected to replace him.
