New Barcelona manager
Vilanova was Guardiola's assistant throughout a trophy-laden four-year period in charge and, after reuniting with his players who were not on international duty this northern summer, he is looking forward to incorporating those involved in the European championships in the coming weeks.
He told AS: "Guardiola and I spent five years together and the first day seems strange, but we have to get used to it because this is what we will encounter all season.
