Cristiano Ronaldo has thrown down the gauntlet to Real Madrid with the threat of returning to Manchester United this summer.The Sun says he is demanding a staggering £32million-a-year deal to stop him from returning to Manchester United.

Real Madrid superstar Ronaldo is considering his options at the Bernabeu and knows United will welcome him back with open arms.

Ronaldo wants an annual wage of £17m from Madrid, which works out at about £345,000 per week.

But he is also demanding 100 per cent of his image rights contract from the club, which could be worth as much as £15m per year.

Even a club as rich as Real Madrid have been shocked by the figures being bandied around by Ronaldo's representatives.

And they are hoping they are just the player's opening gambit in what could be long, complicated contract negotiations.
