Bayern Munich captain Philipp Lahm insists he was open with former coach Louis van Gaal.
The Dutchman was sacked after last weekend's 1-1 draw at Nurnberg, with Andries Jonker placed in temporary charge until Jupp Heynckes begins a two-year contract in the summer.
Lahm felt Bayern played an expansive game under Van Gaal and although it paid dividends last season, the German giants are struggling to even qualify for the Champions League this term.
The Germany international, 27, admits he had reservations about Van Gaal's tactics but claims he shared those with the former Ajax and Barcelona coach and holds no grudges.
"We played an attacking style," he told BILD. "We always took a lot of risks going forward.
"Often we were too far up on the pitch and left space for opposition teams to make too many goalscoring opportunities.
"I have been upfront with Louis van Gaal when it came down to my opinion on our playing style.
"I liked the way he spoke to us, it was always a very honest way and he definitely had success with us last season. We won the Bundesliga, the German Cup and we went on to become runners-up in the Champions League.
"We will win nothing this season, though. We are at Bayern Munich, success is a top priority here. If there is no success, things will be changed. Everyone has to accept this."
Bayern president Uli Hoeness pointed to Van Gaal's decision to drop veteran keeper Hans-Jorg Butt in favour of Thomas Kraft in January as a key factor in his departure.
The 22-year-old's poor clearance against Nurnberg gifted Christian Eigler a second-half equaliser and the following day Van Gaal was gone.
But Kraft, who is out of contract in the summer and may well have played his last game for Bayern with Jonker set to recall Butt, is determined to prove Hoeness wrong.
"It was a statement against me and I plan to come up with the right answer at the right time in the future," Kraft told Munich-based tabloid TZ.
"The goal against Nurnberg was my fault, but otherwise I have not done anything wrong."
