Cristiano Ronaldo will return to Old Trafford after a four-year absence on March 5 after Real Madrid were drawn against Manchester United in the first knockout round of the Champions League.
Even though he will be wearing opposition colours, Ronaldo is assured of a warm welcome from the United faithful as a mark of recognition for his six-season stint that brought three Premier League titles, the Champions League and saw him crowned world player of the year.
Here we take a look at the stand-out moments of Ronaldo's time with the Red Devils.
