I'd still prefer paying 20-30M for Odriozola than 60M for Bellerin who is also far from guaranteed to succeed here.
He's better than Palencia and think he'd be ready to take over our RB spot.
I can't believe that he could be ready for a starting spot after playing just 15-16 games in La Liga ... I think it would be better to give a chance to Palencia and if he does not prove to be good enough for the first team, then we could go for Odriozola next summer ...
Regarding the first sentence, I even prefer keeping Roberto at right back and promoting Palencia then paying such a huge amount for Bellerin ...
Overall, the right back situation and current options all look really risky, so I honestly don't know which would be the best option for us ...
