Owen Farrell, George Ford and Marcus Smith will battle for the England fly-half jersey and Dylan Hartley selected his preferred 10 for the Rugby World Cup.
George Ford said England's players have been teasing Marcus Smith about him using rumoured interest from Racing 92 as "leverage" for a new Harlequins deal.
England international George Ford is looking to drive Sale Sharks to their first Premiership title in 17 years as they reach the business end of the season.
