Stewart Robson may be an Arsenal legend but that hasn’t hindered him from airing his voice on Chelsea.
Robson, 57, made over 150 appearances for the Gunners between 1981 And 1987.
Since quitting the pitch, he has taken to broadcasting and the Essex-native may have stepped Blue toes with his latest remarks.
Robson claims the 29-year-old is inconsistent – citing the World Cup as an instance.
Willian was substituted at halftime in Brazil’s two matches in Russia – something quite shocking for the Arsenal legend.
The Brazilian is linked to Barcelona and Manchester United – with the former’s bid of around £50m reportedly turned down.
Jose Mourinho, meanwhile, is keeping close tabs due to their great relationship.
“Willian is inconsistent,” he told ESPN FC.
“He can be the best player on the field, he can be absolutely outstanding.
“On another day he can play poorly, as was the case in this World Cup where he was taken off at halftime in two of the games.
“I think he hasn’t been happy at Chelsea for a while, he doesn’t always start there.
“He will be looking to see who the next manager is.
“But I think Willian, with his quality, he’ll be leaving Chelsea.”
