I'm not really banking on the academy and loaners I'm simply arguing they are better as backups than spending money another player. It's not the colossal risk ppl think it is. Klopp gives Woodburn and Trent a chance because playing one youth player (your best) around your top players isn't as much of a liability as ppl think. They improve and shine in these circumstances as well.
I will also disagree that Peps legacy is tarnished, if we have to spend 200m in the transfer window, Pep wins the league and youth weren't given a chance, then people will say Pep won because of money. It's so obvious to me everyone would say that and they'd be right.
Our season has been hampered by massive injuries: kompany, Delph, gundogan, Jesus that makes us think our squad sucks, but looking back I think really the fullbacks just need to be addressed and maybe a goalkeeper (I don't think Pep will do this). The attack is young and will get better with time and truly doesn't need bolstering with what's coming in.
In regards to attacking midfielders, Silva is definitely one, can't be argued. Just because Pep plays with floating 8s doesn't change the kind of player he is, fast, agile, dribbler and can thread a through ball to our forwards (I honestly think Sterling can fit this mold but that is another discussion). Silva is also regularly the most forward of our 3 midfielders and becomes the second striker when we press in a 442. Kevin is an attacking midfielders but not agile or quick enough, he is kind of like Kroos. A more pure attacker like Silva is need imo but I already mentioned we have good backup in loanees and the academy to him.
