For the two side finals it is great.

Some players are good when you start them from the bench, just like Elanga at Man United he is good from the bench as compared to his starts. However everyone wants to get enough playing time hence will not agree to be started from the bench. Now that he is getting the playing time too things are not good.

Some coaches are also afraid to start players who performed in their previous matches from the bench from the bench again. All this are contributing factors.
