However, Saha that the criticism directed at the Portuguese playmaker is unjust and could even push him toward an exit from Old Trafford.
Speaking to Genting Casino, the former United forward expressed his fears that excessive criticism might force Fernandes to consider his options.
"He could be tempted because, yes, he has proved over the years that he plays to a certain standard. He plays really well and is still being harshly attacked," Saha said. "I always come to the defence of Bruno because, as I said, I try to explain what I see and I think it's completely unfair. It’s interesting that Roy Keane has criticised him. I understand and I respect his point because he knows his position. He knows what leaders need to do. That's not easy when you are a fan, you criticise harshly. But I would still say it is harsh, because Bruno deserves respect, and as a human being you make mistakes and all sorts."
