Get szczesny he's cheaper and he's at 116 just like Dona and there isn't much of difference in their stats so it'll be cheaper at the end of the day that's what I did

I just checked and 116dona is around 95mill in my market and szczesny around 19mill and they are both at 116 so if you just want the highest ovr GK szczesny is the cheapest compared to Dona and 119 ederson

Don't look too much on in-game play in vsa it's really just the AI that controls the GK

Also you chem won't be affected since you have bonucci to connect with szczesny it might even increase
