He said: "There are one or two who are disappointed with their performance, but the most important thing is that we try and put it right on the training ground with a view to next Saturday.

"The be-all and end-all is that the XI that started have the shirt and have got to keep hold of the shirt.

"But I don't think anybody can come and knock on my door if they are left out of the team after that."
