Need of buffering champions donnamura

My 121 rated donnarumma has a serious problem .it doesn't make sense that my goalkeeper can't keep up  against low rated attackers (outdated) .If he can't  keep up with low rated forwards how those he keep against world games Gordon or champions Diaz many 119Gk are better than him right now the likes of Allison ,safonov,neuer, Sanchez,world's game courtois are better than him in head to head  his poor keeping gives a way goals costing loss to millions of players in h2h, vsatt . I don't think the problem is ovr:player setup or program I would like to buff him cous it give me fuel to see ur defense get /got torn apart by khvica and ur GK save the shot  or u as the opponent seeing ur shot being stop by donnarumma (know it going to tuff to beat this GK )  pls i would like for you to take a look at my complaint  

Thank You
