Speaking to reporters, the former England striker said, "I think some players in there need to grow a pair of balls, basically, because I’m watching what they do in training and the minute there are fans out there they become a different player, a different person. That is football. You are going to have to play in front of fans, wherever you play.
"It is okay doing things on the training pitch but you have to take that into the games. We are still a young team but then the leaders in the team… that’s where Jukey (Jutkiewicz) has been brilliant. He is frustrated he doesn’t play all the games but you can see he is a leader, he is talking in there. But there are some players who have got enough experience to stand up and be leaders. They are trying but it’s silly errors, and decision-making. Game management is a big part of the game we need to improve on."
