It would be criminal not to give Samper a chance. I'm among those that have doubts about his potential to succeed but he should get a full and fair chance to prove himself. This player is the epitome of La Masia, having worked his way up from FCB Escola at the age of 6 to playing for the first team. He has always demonstrated 100% loyalty in every stage of his career so far, having rejected Arsenal at 16 and saying that he didn't even want to go on loan because he wants to play for Barcelona so badly. He's always said that he's a 100% Cule through and through. On top of that, he's a player who's demonstrated great footballing intelligence and understanding of Barca as a club and as a footballing team.
If Gomes can be gifted with unwavering confidence/loyalty for an apparent lack of effort and talent, then surely Samper deserves a full season in the squad. The club has shown its willingness to de-prioritize La Masia in recent years with Thiago/Grimaldo/etc. being let go far too easily without the trust to continue forward with the team. If the club can't respect a player like Samper enough to reward his absolute loyalty with at least 1 full season in the first team, then the words 'Mes que un Club' mean nothing to them.
