If we don't get Danilo, we should go for Bellerin but that's a ''bad'' habit from me that I always consider a player's potential for the future instead of soley focusing on his current level. Danilo would probably be able to take over the Alves role pretty easily and he is still my first choice since it's extremely rare to get a good/great RB nowadays but Bellerin is only 19 and is currently in good form at Arsenal. He's 4 years younger than Danilo and I wonder, if he'll surpass Danilo's current level when he becomes 23. With 4 years at top level it's not even close to impossible.
