Throughout the years we've seen United changing strategy at least twice. We had SAF's value strategy which saw us keeping old players past their expiry date and replacing the likes of Giggs (on the flanks) and Ronaldo with 'talent' like Young and Valencia. The likes of Aguero, Hazard and co were just too expensive for us especially since it also meant giving money to agents for services rendered. Afterwards we went in full panic mode, spending millions on players who were either not good enough (Fellaini) or couldn't fit in our system (Mata and ADM) just because we could. That didn't served us well either.
I believe that Mou is introducing a third way. He's bringing the quality players he need, if possible, as a bargain.Ibra, Bailly and Mkhitaryan were probably the best EPL bargains this year. However if there's that quality talent who would fit our system perfectly and he's available then the fee shouldn't be an issue. That's how top clubs should work. The biggest club in the world can neither be skint nor stupid.
Some people are underestimating Pogba. He's the typical complete type of midfielder (he's strong, he's fast, he's technically gifted, he's got workrate, he's got great passing ability etc), he's at the right age and the fact that he had already been in Manchester, he won't struggle to adapt. Also he's a homegrown talent (its rare these days that we've got top quality homegrown talent). He's also a big name signing which United merchandising machine will milk to its fullest and which would show the world that United is back.
