Real Madrid will soon discover that £80 million will NOT be enough to land Manchester United star Cristiano Ronaldo, it has been revealed.

The Daily Mail says Real have a transfer fund of 100m euros - around £80m - and could go 'all in' to call United's bluff and test their resolve. Such a deal would blow the £47m world record they paid Juventus in 2001 for Zinedine Zidane out of the water.

But United's owning Glazer family, guided by chief executive David Gill and manager Sir Alex Ferguson, are likely to reject even that sum. They are determined that they will not blink first in their power struggle of a face-off with their only rivals as the biggest football club on the planet.
