Maybe if you had rotated more in the 2nd half of the season like you should have this wouldn't have become a problem then?!
It is quite literally your own fault that this is a problem - not like those you are actually choosing look to be physically prepared anyway

Explaining his team selection amid three games in a week, Maresca said: “I spoke with some of them, they all said that they were recovered and they were okay. The reason why we changed three players was because of that.
“At this stage of the season, to make six or seven changes, probably it’s difficult compared to the beginning of the season when we did it many times. Now it’s more complicated. The reason why is that the players who are playing now are physically a little bit more prepared compared to the players that are a long time not getting minutes.”
