I think this is about right. Barry was self evidently better than De Jong in the eyes of the manager. Barry was the best of that bunch but he was essentially replaced by Fernandinho. De Jong did bring added personality and aggression to the equation but, for example, he was never likely to score a goal and even Nando does that occasionally.
I have no idea if he will stay or go but I do believe that his first season was messed up by one hospital pass by Kolarov against Stoke; in fact, if I had to pick one single moment that screwed up last season's campaign, it would be that. If Nando had not got injured then, I doubt we would have lost that game...
I am one of those who consider Nando to have been one of the team's better players in the final phase of this season but I have no prediction on whether he will stay or go. What I am optimistic about is that the combination of Pep and, hopefully, some serious improvement of the playing resources over the summer will help to bring the best out of the players that remain from the current squad: I think part of the problem has been a lack of belief and confidence on the part of too many players.
