Rubbish mate, it's entirely about what team is best to get the result on Saturday that matters and with one eye on the team he will want for the cup in mind as well
For everyone saying can't drop a bloke who comes on as a sub and scores a hatrick, what exactly is the benchmark for a sub becoming a must start player the next game, 1 goal, 2 goals, 3? how many assists would mean you have to start him, or if he's say a cb is their a number of blocks, tackles or headers won that you then say he must start the following week?
Also, how long does it give you credit for? 1 game, 2 or until the next sub hits the right number
