Sunderland boss Martin O'Neill refuses to gloat over the success of £12 million signing Steven Fletcher.

Rather than scoff at those who questioned the size of the fee, O'Neill says the Scotland international should be judged over a full season instead of just a handful of games.

Asked whether Fletcher has vindicated O'Neill's faith in him, the manager told the Sunday Sun: "I would love to say that is the case. He has scored five goals and played very well for us.

"However, and I am sure Steven will take this in the right way, I am not sure six or seven games is any great proof.

"He has made a great start. I am delighted with that. I think it is some justification for things.

"Vindication, I think, comes at maybe the end of a season.

"I would not be rushing out and making judgements on six or seven games and telling you he is worth every penny. Time will tell but he will do it."
