A good manager is supposed to adapt and work with what he's got, no? He obviously won't play with Neymar and Messi as wingers unless he's really stubborn and looking to self-destruct. Rational way to go is to keep Messi as false 9 and sign a tall striker for plan B. Unless, of course, Messi is sold this summer. But sporting reasons aside, I still don't see it happening as he's our golden hen and is probably worth even more than 250 mil. of his buyout fee.
