George Groves has admitted this weekend’s clash against Badou Jack might be the last chance he gets at a world title, whilst also insisting he no longer cares what Carl Froch thinks. Groves will fight on Floyd Mayweather’s undercard this Saturday, and brushed off criticism from Froch, saying 'he’s just a retired fighter’. Meanwhile Paula Radcliffe has hit out at claims she is a drugs cheat. The 41-year-old categorically denied ever doping during her illustrious career despite being implicated in a Parliamentary hearing. In golf Rory McIlroy has admitted he doesn’t think Louis van Gaal is the right man to lead Manchester United. The Irishman, obviously a firm United fan, said he liked the signings, but didn’t think Van Gaal was ideal. Lastly Wayne Rooney became England’s all-time leading scorer last night after hammering home a penalty against Switzerland.
