"We need change from top to bottom," Gerard Pique said but even he could not have predicted what followed as Barcelona, without Lionel Messi, reunite with Bayern Munich on Tuesday, a year on from the defeat that changed everything.

After the 8-2 loss by Bayern in the Champions League quarter-finals, Pique said Barca needed change of all kinds, "not just players and coaches, but structurally", insisting "new blood" was needed. "We are not able to compete in Europe," he said.
