Agreed, at this point in the window, I can’t see us bringing in more than 2 players. One of those players will almost definitely be a CM and next would be defence, CB, RB or LB.
In terms of numbers, on paper we’re ‘well stocked’ as we have 4 CBs, 2 LBs and only one RB on the books. In an ideal world we’d get players in each position, but if we have to prioritise, CB is top. CB is the most important and some experience is needed there in particular. We’ve already conceded 3 preventable goals and it was an Achilles heel last season because we couldn’t keep a clean sheet. Lati is already the 2nd choice RB in the depth chart and he’s good enough defensively for it to work.
As for CM, a lot has been made that we’ve got the numbers, perhaps. The quality isn’t there, our midfield looks unconvincing without Sheaf as it did last season hence we tried to sign Browne, Stamenic and others. In particular, Allen is not at the standard required - he’s a useful rotational player at best imo.
It’s worth noting that Robins spent the tail end of last season stating how he needed more quality in midfield, to not sign anyone new in the transfer window would be strange if that was his choice.
