With bad gameplay, cr7 is horrible though every player will be horrible in bad conditions. Like others said, he does tip over a lot and will lose the ball at times. However, he'll just score goals for you. Heading seems 'fixed' with him. I have Mbappe too as my other ST. You will need someone fast and agile as a co-ST with cr7 if using 2 st formation. Using a 442, 41212n, and 352 at the moment.
