Lol Jack may be in general calling Barca then chokers, and isnt thinking of De La Pena individually much, but as a player, I would say yeah was a choker. Barca then were too much of a rollercoaster and no real foundation, but that had nothing to do with why De La Pena has had an underwhelming career considering his talent. He didnt have the mentality to take center stage, was considered a big talent/hope for the future like Xavi (first Guardiola successor before Xavi). But was waaaaaay to inconsistent and generally pissed his carer away, atleast to what it could have become, because he didnt have the right mentality, couldnt handle the pressure of that level at all.
Xavi was also close to giving up mentally like De La Pena did, he said it himself, stopped believing in making it and was close to Milan etc.
But regarding Luis Enrique, interesting Roma are taking such a risk, but it will be intriguing to see what he can bring to Italian football.
