Stoke City lose Marc Wilson for three months with broken leg as Adam Johnson urges Sunderland to work harder But I also think we need to create more chances. James and I and the other midfielders need to work harder for the strikers. Right now, Johnson looks a shadow of the player who at times electrified the Etihad Stadium. O'Neill, who has urged Johnson to stop trying to win games on his own, is confident the player will come good. "At the moment Steven is our goalscorer, we need to and are trying to address it," O'Neill said. Adam got injured training for England and it has been a bit stop start for him. But I have no doubt in time he will be terrific for us. He will be able to create and maybe as a consequence we'll be able to share a few goals around. One Sunderland player on top of his game at present is Simon Mignolet, who made two excellent saves to keep out late headers from Robert Huth who, at the opposite end, blocked a goal bound Fletcher shot with his hand, yet escaped sanction from referee Mark Halsey. Stoke's concerns on Sunday revolved entirely around Wilson, who is facing three months out with a broken fibula after being injured in a clash with Fletcher on Saturday, and was immediately taken to hospital. The defender's dismay was at least tempered by the offer of a four-year contract extension, which he is expected to sign on Monday.
