Barcelona are concerned with Pep Guardiola being back in the city this week.
The new Bayern Munich coach was in Barcelona for a local conference, but there is a feeling at Barca he is also talking to his old staff.
Technical scouts Domènec Torrent and Carles Planchart have already been linked with a move to Bayern, while it is assumed coach Manuel Estiarte will also follow Guardiola to Munich.
The troubling aspect for Barca is that apart from Tito Vilanova, Jordi Roura and Aureli Altimira, all other football staff are contracted only until June.
