After about a week of using Gold CR7, I can't see myself using anyone else at Striker for the forseeable. I find him way more effective and fun than I did Mbappe. I think you must use Engine on him to boost his dribbling and pace, his shooting is already ridiculous enough already, and the passing boost it gives him makes his the complete forward, he gets tonnes of assists for me playing with Mertens just behind. I just never get bored of his rocket shots. I've never found his balance an issue, but then again with Engine it's 81 which isn't too low.
