Manchester United have joined the battle for Liverpool midfielder Raheem Sterling.The Sun says United will launch an audacious bid for Sterling this summer.

With no player having made the move from Anfield to Old Trafford in over 80 years, Sterling could be on the verge of an unprecedented move between England's two-most decorated clubs.

Sterling, who has two years left on his existing deal at Anfield, is reported to have turned down an improved £100,000-a-week deal with the Merseyside club.

United are reportedly willing to pay £50m for the England forward's services.
