Sorry Gruj but they aren't different options, they are just different people doing more or less the same thing (with the possible exception of Mane).
Of course they can be very different, do you not think it possible to coach two different ways so that when a certain player comes on (without the need through injury) the players think "ahh, plan B" ?
Lets be honest, we all sit watching a game and when a certain player comes on we think oh, they are going long or maybe, they're going to sit back and try to hit them on the break if it's a fast or tall player, sometimes an extra midfielder may be brought on because you are getting over run there. The game is not one set plan and we all can see and know that so to say a certain player will not fit in is silly, the others are well used to changing style as required, or should be.
