It has to be 07/08 for me where he got the 42 goals and led us to the double. Even though he's gone on to regularly beat those goalscoring numbers at Real I feel like that season he achieved the perfect balance in his transition as a player between early, flashy Ronaldo and the current machine-like clinical Ronaldo. Plus a vast many of his goals in that season were game winners as we were a fairly solid, defensive team in some ways and ground out many 1-0, 2-0 type wins. There could well be a huge amount of bias in having that view due to being a United fan though.
