United's Premier League and Champions League Double seemingly won't stop Sir Alex Ferguson further strengthening his squad this summer - with a striker apparently top of the list.

The UK press are tipping the Reds to move for Lyon's Karim Benzema, Ajax front man Klaas Jan Huntelaar and Blackburn striker Roque Santa Cruz. Prices range from £15million up to £30m.

Sir Alex is also said to be closely monitoring the contract situation of Manchester City's up-and-coming 18-year-old striker Daniel Sturridge.

United have already been beaten to one summer signing, with Cardiff City's highly-rated midfielder Aaron Ramsey opting for a move to Arsenal for a reported £5m.
