Pep Guardiola doesn't forget and doesn't forgive when it comes to Cristiano Ronaldo, after the former Barcelona coach refused to shake the Real Madrid forward's hand at the Ballon d'Or awards ceremony.

The dashingly attired Ronaldo offered his hand to the Catalan, sat in the row in front of him, only for Guardiola to swiftly reject him after making eye contact for a second.

The snub perhaps stems from when Barça battered Madrid 5-0 in the November 2010 Clásico.

Ronaldo gave Guardiola a mild shove in the chest on the touchline as he held on to the ball, only for the then Blaugrana coach to clutch his face.

It perhaps makes the chances of the two uniting remote. Guardiola is touted as Sir Alex Ferguson's Manchester United replacement, and Ronaldo, is often touted for a Manchester United return.
