we should sign Cote, as we have. I wouldn't have thought of him specifically but it fits what I was talking about with Sakho. he replaces Maxwell, so we have 3 LB's, but I think Bilal will operate as our 3rd choice CB with Bartra taking the role of 4th choice and also backup RB (with Sakho we could just use La Masia to back up Dani, as Sakho can play CB too). we don't need to sign a specialist CB now, especially as Badger & Busquets can play CB if needs be (which is something I hadn't really considered when vaunting Sakho).
the advantages of Cote are he's cheaper and Spanish, so adaptation time will take less, we'll have more to spend elsewhere, and he'll have the chance for club & country linkups for many years to come, should he kick on as he should.
Sakho would have been more proven, but also a bit too much like squad stacking given he's essentially identical to Abidal in his style & versatility. and as much as I love Botia, he is a specialist CB so bringing him back, while awesome, would probably be a waste (more squad stacking) as he'd not be likely to see as much gametime as he should. still wouldn't complain if we did bring him back, as it'd only be for €2m.
then we should also sign Cesc, for sure.
then Sanchez (of those listed) for the forward line. though part of me would like to see us get Kun Aguero for that spot.
I also selected Pastore, who I reckon could play in either of the lines and is for sure great chums with Messi. so if all else fails we could bring him in.
