I say we go to big either this window or summer either pre euros (so the prices aren't hugely inflated) or we will be having our pants pulled down. For mediocre players. Again.
LB - Digne
CB - Uppemencano
DMF - not a clue. Partey looked ideal (as did Rodri)
CMF - We're OK here. I dont like Ilkay but I see with legs around him he's a terrific player, needs options from players ala David Silva and legs like 28/29 year old Fernandinho around him.
AMF - like has been said - Grealish IS the best option.
Forward - Martinez or Dybala, Messi, Haaland. Maybe blood Braff?
Throw the kitchen sink at it. We've not rocked the market for years. Just do it. Use January and summer to put this in place, Pep signs his extension and rebuild part 3/4/5 comes into fruition. If we buy these kind of players after a storming Euros or we buy the next flash in the pan International star (there's been a few, Poborsky to name one ) after a decent euros we pay through the nose.
