I have Messi in my Southampton team, playing against the mighty Man City. He scored a goal and assisted another. Then suddenly the match engine substituted him for an 80 player! No wonder the game changed and I conceded 2 successive goals to lose!

That was one of the most ridiculous substitutions I've ever seen. Is there any way to avoid that? I thought not to put subs, but what if one of my players got injured?
