1. He's doesn't have to be tall or physically to be a fullback. Johan Cruyff once said that he rather prefer an intelligent smart player with technical abilities than being physical and strong. Alves and Alba are not phycial or strong. Bellerin, Roberto and Vidal aren't either. Never ever mention physical to me because if you do, please support a PL club. Johan cruyff played a physically weak Pep Guardiola because because he was intelligent. Pep played a physically weak Busquets instead of Keita for the same reason. Both Pep and Busi did the dirty job. Don't tell me I can't compare a DM to a FB in terms of defending because both of them have to use their brain to defend and not their body like physically strong PL players. Palencia is a solid defender and I haven't seen any bad games of him. Impossible to run past him. In terms of attacking he needs to improve a little bit, but that is something every newly promoted players have to do. He intercept the ball easy because of his intelligent brain, not with his body.
2. You are saying Aleña is good to be a possible first team player, but did you know that Palencia had a better season than him? I followed every Barca B games last season and Palencia was clearly the best player. But ofc Aleña can be a good first team player for playing against 6/7 tier players, but not Palencia when he was definitely the best player last season? Where is your logic? If players from the third division is 6/7 tier players, then I can say Busquets and Pedro played against 9/10 tier players. You can't even tell me why Busquets was prefered by Pep instead of Alonso. You will say he was good enough, but still haven't watched him play for the B team unlike me. And by the way he played in a worse league than Palencia, but both impressed. You should understand that Barca promote players from second, third and fourth division if they impress. So next summer Aleña and Palencia should be promoted to the first team for their fantastic season no matter division. They even won promotion to the second division and doing great there aswell. You clearly don't watch barca B games if you think Palencia hasn't been a standout player.
3. Roberto and Vidal both failed to impress against a third division team like Hercules when we played them in copa del rey whilst Palencia was MOTM against the same team. Bellerin is shit against a big, mid, small and even a championship team in PL. All of them are not players you prefer because they are not physically strong or tall so why overhype them? Atleast I can say why they are shit unlike you.
4. I compared Abidal and Palencia because they both defends more than they attack? Can you read? Didn't say he was good as Abidal.
5. Yes it's confirmed. There is a reason he renewed his contract + has a higher release clause because Barca count on him. Only him, Aleña and Cucurella from Barca B have all renewed their contract with a higher release clause. 50M for Palencia if he reach the first team and 75M for Aleña. There is a reason for why the release clause is higher if they get promoted because Barca count on them.
6. Puyol, Busquets and Pedro didn't play for spain at any level either, but suddenly recognized by Spain when they reached the first team at age of 20-21. but they become the real deal, didn't they? In Puyol's case he was shit like Palencia when he was younger. Then Barca wanted to sell him to Malaga, but he refused to leave and worked hard and the rest is a history. Palencia was a nothing player, but worked hard and today is the best player in Barca B along with Aleña + captain for the team.
7. If you think Gumbau had a better season than Marlon, then you are either stupid or you are lying about watching Barca B played last season. Marlon was third best player after Palencia and Aleña and there is a reason why he was promoted to Barca first team and now loaned out so he can play many games and come back whilst Gumbau is playing for Leganes. Clearly stupid thing to say, don't you think?
