As the post says guys, I'm really struggling to hold on to leads in a new career save. My players, some but not all, seem to flat out run out of steam about minute 54' in the game.

I thought this was more stamina rating related or high pressing so I played with high stamina players and changed tactics to possession football with less pressing and a slow build up. I was averaging 64% possession but still the same result.

Is/Has anyone had the same issues?

My guess is that it could be the new update because this has not happened in previous save.

Fyi my team is Sunderland and I started in the League One, I invested in young potential players and youth players. Maybe that could also be another reason, although some have really great physical attributes.

Any help would be appreciated! Thanks guys
