I was lucky enough to get CR7 in my player picks. i haven't played with his normal gold card yet so i can't say if he's worth the extra 700k but let me tell you CR7 is the definition of the perfect forward. i play him in a 451 and switch in game to a 4222. I played him at striker as i found he performs better in this position and used an Engine chem style on him and partnered him up with Mbappe and these two go better together then peanut butter and jelly. he's scored 28 goals and 11 assists in 14 matches so far during champs.
Ronaldo is rapid especially with the fake shot speed boosts, his runs in behind and amazing and he always seems to be in the right place at the right time. he's also strong enough the hold off the toughest of defenders and is clinical inside and outside the box even when under pressure. his stamina wasn't a problem for me and his play making was surprisingly good. his best attribute is his shooting obviously. its the best i've seen in this game, he is deadly on both feet. No matter where he is he always finds the back of the net, even when the keeper gets a hand to it and his finesse shots from outside the box are superb.
He doesn't feel as fluid as the likes of Hazard, Neymar or Messi. People also tend to man mark him in game which may make it difficult to get him involved but i found it helpful if i just played normally with my other players and waited for Ronaldo to find space or get in behind. I also don't know if theres much of a difference between his normal card and this one to justify the 700k+ upgrade.
