West Ham co-chairman David Sullivan has revealed they're undergoing a huge overhaul of their scouting system.
Sullivan concedes they've made mistakes in the market this past year.
"Going forward, we are going to completely re-jig it," Sullivan said. "I am going to delegate the whole thing to a huge new analysis system and a new head of recruitment, massive video analysis department, increase the scouting, every player will be looked at five or six times.
"We wont be signing a player based on who the manager has never seen play. The manager will watch him play and we hope we will spend our money better."
