Rio Ferdinand insists there will be no love lost for Cristiano Ronaldo if Manchester United meet Real Madrid in the UEFA Champions League.
The Portugal international spent six successful seasons at Old Trafford before sealing his world record £80million transfer to Real over the summer.

The teams could be paired against each other in the latter stages of the competition and Ferdinand would relish going head-to-head with his former team-mate.

"You want to play against the best players, and he is the best.
