Pep Guardiola insists it is premature to discuss a possible exit from Bayern Munich as he prepares for Saturday's German Supercup against Wolfsburg.
The Catalan is entering the final year of his contract with the German champions, and has so far appeared reluctant to sign a new one with speculation growing that he could head to Manchester City next summer.
Former Bayern captain Stefan Effenberg told German Sky television on Friday that he is "pretty certain" that Guardiola will be leaving in 2016, but the 44-year-old Spaniard insisted nothing had been decided.
"This is the first and the last time that I will talk about it," Guardiola said. "I am coach of Bayern.
"I am grateful to be here. I have not yet decided what the best thing for the club is, but I am doing my best and I will do my best.
"I have not decided yet. Maybe Effenberg, who was a great legend for Bayern, knows more about it than me, maybe I should give him a call.
"I've not received an offer from any other club in the world. I'm very happy here.
"When the moment comes that I do make up my mind, then I will inform [chairman] Karl-Heinz Rummenigge, [former president] Uli Hoeness and [director of sport] Matthias Sammer.
"I've read lots of things lately, but all I care about is the good of this club. I will never become a burden for Bayern."
Since taking charge of Bayern two season ago, Guardiola has led them to the Bundesliga title twice, also collecting the UEFA Super Cup, the FIFA Club World Cup, and DFB-Pokal.
The German Supercup is one of the only two trophies to elude Bayern under his charge, with the Champions League the other.
"Every title is important for me," Guardiola said. "The Supercup's a big title for me and I want to win it.
"If we do win it, then we'll come back to Munich the day after with a smile on our faces, if not we'll be sad."
Saturday's match will be played in the VW-Arena, where Wolfsburg did not lose a single Bundesliga game last season, and enjoyed a 4-1 win over Bayern in January.
"We won the title in the end, and that is the most important thing," Guardiola said when reminded of that match.
Guardiola could give a debut to new signing Arturo Vidal with Arjen Robben also available.
His opposite number Dieter Hecking will also have to wait before deciding whether one of his key players, Kevin De Bruyne, is fit to play, although Guardiola hopes to see the Belgian lining up against his side.
"I want to see the best Wolfsburg team," he said. "I hope De Bruyne plays.
"It's going to be a top-quality final. Wolfsburg were runners-up last season and played a great campaign."
