"Not unless the club has recruited and has someone coming in through the pipeline. It’s important for the manager to have the right amount of players in training and the right amount of players in the defensive midfield area," Silvestre said. "Of course you have Kobbie Mainoo but besides him, you can’t identify another top number six in the squad. There's still another three weeks until the window shuts. I wouldn't be shocked if Casemiro was playing for another season, it's not like United are challenging for the title so I think if you consider this period as a transition, he could still be a good leader in that squad."
