Manchester United are set to announce the signing of four top stars to new contracts.

The Sun says United will spend a staggering £90million in wages to keep four of their stars.

The club are splashing the cash on mega salaries for Cristiano Ronaldo, Rio Ferdinand, Wes Brown and Michael Carrick as the quartet tie up lucrative new deals.

Brown and Carrick have followed Ferdinand by agreeing contracts - which means in the last week United have committed themselves to £52m in wages.

And Portuguese genius Ronaldo, 23, is ready to seal a five-year, £150,000-a-week deal in the summer, taking the total figure to £90m.
