Barcelona playmaker Andres Iniesta has stressed the importance of Pep Guardiola at the Nou Camp.
The manager's contract is set to expire at the end of the season, with fears already starting to surface in Catalonia over the long-term future of one of the club's most successful leaders.
Despite spending just three years in charge, Frank Rijkaard's replacement has claimed two Champions League trophies and the La Liga title every season of his reign, and Iniesta insists the player's remain 100% behind their boss.
"We will always say the same thing and that is that we are very happy with Pep Guardiola. He is fundamental for Barcelona's project," Iniesta told Spanish publication Sport.
"If the coach decides to stay on, it's because he still feels he can be successful. He has said more than once that it will be difficult to stay on once he doesn't have this feeling.
"It is not about what we can offer the coach or what he can provide for us. The key is that we are one team and that we have to give 100 per cent.
"There's little more you can ask for than doing your utmost, and there's a good understanding about this between the players and the coach."
Whilst many believe Guardiola to be one of the best managers of his generation, the man himself has hailed arch-rival Jose Mourinho as the current great.
The Real Madrid manager is trying to wrestle the title from Barca's grip this season, and could have a chance with 'the special one' at the helm.
"It is not necessary to have played football to become a great coach. [Arrigo] Sacchi changed this sport without having played, while Mourinho is probably the best coach in the world," said Guardiola on management.
"To have been in dressing rooms before can help in certain situations, but to not have been can also have advantages."
