Game lags after first half , FPS drops and the game is unplayable

My game runs perfectly at first — smooth in both the menu and during matches. However, after the first half in Ultimate Team especially rivals matches , it starts to lag badly, with heavy FPS drops and noticeable input delay. It becomes unplayable. That made me lose too many matches even tho i was winning in the first half.
