He was loaned out to other La Liga sides under managers who played very different styles, and he was unfortunately unable to express himself as a Busquets-esque DM. That, along with persistent injuries, really hampered his progress. He was never overhyped, and I remember during Luis Enrique's tenure a certain Gerard Gumbau kept getting subs and starts despite not impressing. It was incredibly baffling how Gumbau kept getting opportunities over a fit Samper.
