I actually think the squad is shaping up well for Poch funnily enough - as i said previously Porro can play RB and did exclusively prior to joining Sporting (check his thread there's a post with a link to a Portuguese journo who was talking about it) A young left sided wingback like Udogie should be moldable to play an attacking full back role, afterall that was essentially the plan for Sess with Poch, wasn't it? If not we need a new Left Back - i think we're in for 2 CBs come the summer, one or both will be reasonably young and this will give us 3 (along with Romero) competing for 2 positions, not an issue and actually a sign of good depth- we wpuld need to sell an extra one of the old guard though in this scenario I'd have thought. Our pool of CMs match up well wuth what Poch would want, Bissouma & Sarr especially imv. Kulu/Kane would be options currently at AM but yeah we'd likely need to invest here (Maddisonon??)
So yeah a LB & an AM to be signed as i see it as worst case scenario (assuming 2 x CBs & GK come in already)
