I wouldnt bother splashing 30 million on Isco. If we plan to play two up top then we already have Sterling, Coutino, Lallana etc who can play that number 10 role. Gerrard can play there too, Suso, Tex. It's just not a position we need to majorly strengthen. Not sure how he goes in a wide position in a 4-3-3 but again we have many options. If Balo is up top then you have Coutinho, Sterling, Markovic, Sturridge, Suso, Lallana etc all capable of playing those spots.
We need more help in midfield and if were spunking 30 million, then perhaps on a striker, not another AM.
I'd love Carvalho and id also really like to take on Cabaye who I think is an excellent CM. Would be a massive upgrade on a bloke like Joe Allen.
Im also all for signing Odegaard. If he wants to come which all reports says he does cos he is a massive Liverpool fan then how can we not take the chance just in case he is the next Messi.
