Why was Tito Vilanova so hesitant to use David Villa when he is such a potent force?
When he broke his leg at the Club World Championship against Santos, he was ruled out for the rest of the 2011-12 season. Since then, a 31-year-old with a horrific medical record just doesn't look like the kind of option you want to use week in, week out.
But Villa feels ready to play every five days, and only he knows how strong his leg is.
There's an argument to suggest that if Vilanova was worried about putting too much pressure on him, he unwittingly made him nothing more than a fringe player.
It's also noteworthy that Vilanova played a quicker, more direct game while at the helm compared to Pep Guardiola, and the wide forwards became more important than ever.
If Villa has lost his speed coming off the edge, what good is he?
Barcelona aren't afraid to get rid of players who no longer fit. Samuel Eto'o was the best finisher in the world when they dumped him in exchange for Zlatan Ibrahimovic.
