Im not considering the Porto set up aside from it being a starting thought to compare to (which is more important IMO) what he has done with us so far.
So far WE are looking like a 4231 with a midfield base being a DM and one Box to box, an AM and wide players pushing inside. Given we have one forward the AM has a responsibility to support and offer foal threat.
Jamming Sigurdsson, Sandro, Dembele, Moutinho, VDV, Bale, Lennon into a midfield is simply not feasable - and these are not players willing to be bench warmers IMO.
Looking at Porto, apparently AVB didnt rotate a lot. It was a concern I had when looking into him months ago.
If we have a set up of
..............DM....CM
..................AM
......RW...................LW
..................ST
We are looking at
..........Parker..........Dembele
..........Sandro........Moutinho
..........Livermore
....................VDV
....................Sigurdsson
Lennon....................................Bale
......................Adebayor
Putting VDV, Sigurdsson or Dembele in the wing forward roles might be serviceable but it is not playing to any of these players strengths and if the intention was this all along - compared to just buying wingers - its bloody ridiculous
