1. Sean O’Brien – London Irish
London Irish again wasting money. They have reportedly parted with £450,000 per season to land the experienced Ireland international. Due to a hip injury, the back-rower is yet to play a game, meaning his high-profile move to the Exiles can’t be described as anything other than a flop. He’s admitted to the Irish press that adapting to London life is a slow process, having previously spent his entire career with Leinster.
