It isn't time wasting. You need to pass the ball around and draw out the defensive midfielder and defenders to make space. Otherwise, you just run into a wall of about 6 to 8 opposing players.
You haven't played competitive football before, have you.
Wait wait wait wait wait wait.
Haven't you seen the way they've been passing the ball around lately in future games?
Everyone gets angry at them for this "time wasting" with the ball when they should be playing it in the middle of the pitch, if they keep playing it around, it's more likely the opposition will get the ball however, obviously they might not, I guess it depends on the outlook of the game.
That is all.
