I've not seen tons of him, but he has tended to really frustrate me in the bits I've seen of him.
I maybe do though have a bit of a prejudice against small strikers who aren't obviously smart (cf say vdV, Keane, Soldado etc.). I blame a decade of Defoe (and Bent)
I don't think I agree any more. We've shown more steel and resilience this season than I remember in a long time.
I think we've got a great blend of leaders (Lloris, Verts), organisers (Fazio, Stambouli), experienced pros (Soldado, Vorm, Lennon) and young players with really obvious leadership traits (Bentaleb, Mason, Kane).
One of the great things Poch seems to have done is create a unified (core) group, with a common purpose, obedient to him.
Under freer/more chaotic setup having good things rub off experienced players (e.g. Gudjohnsen, Nelsen) was great. But under a far more structured setup like Poch's, bringing in new influential actors might actually be quite detrimental.
I think that's why Poch wants Moreno - because he's a really strong leader who he knows completely gets what he is trying to do
