After the game, Lewis said: "Of course, there's leaders in the dressing room that are natural leaders.
"They can speak, everyone listens and everyone agrees. But when it comes down to it, it's not what is said in the changing room, it's affecting the pitch and what we're doing on the pitch.
"That's what needs to be solved. Nobody is going onto the pitch saying 'I'm not doing that', or 'I don't want to win'. It's difficult right now but we have to stick together."
