"Our service to the strikers has been shocking. We haven't been providing them with anything - passing or crosses. But I'm confident that will change," midfielder Harper told the Reading Evening Post.
"We have the players. People don't realise how good John Oster is.
"He is brilliant and if he gets a run in the team he'll be great.
"Jimmy Kebe's here as well. Unfortunately for him he hasn't got time to feel his way in. He's got to be at it straight away."
