Frankfurt furious with Bayern's announcement of Kovac as coach

"I'm enjoying life, but it's always a question of financial security", Nagelsmann said, as reported by the Bundesliga's official website.

When the Croatian took over in March 2016, the Eagles were fighting relegation and, despite a slow start, Kovac was able to steer Frankfurt to safety - via a relegation play-off victory.

Frankfurt's sporting director Fredi Bobic was furious, accusing Bayern of being "not professional and disrespectful".

"I think that Bayern behaved very fairly, we have nothing to be blamed for". Hoeness was particularly angered by suggestions that Bayern intentionally leaked the news of Kovac's appointment to the press.

They've managed to win their 28 and 6 in a row Bundesliga title with five games in hand, allowing the club to focus on the Champions League.

At a news conference later Friday, the older Kovac said he had mixed feelings about leaving Frankfurt, but "not many coaches, not many players" get an opportunity at Bayern.

Bayern did not reveal the cost of poaching Kovac, but both Bild and Sport Bild claimed that his departure before the end of his Frankfurt contract in 2019 would cost Bayern 2.2 million euros (S$3.6 million).

"With Liverpool's energy on the counter attack, I thought they would have killed Madrid".

Bayern Munich president Uli Hoeness hit back at Eintracht Frankfurt on Saturday, calling criticism over the hiring of Niko Kovac "rather outrageous".

Kovac said on Friday that he was only offered the job only on Thursday and then made his decision to accept it. "Not of Eintracht Frankfurt".

After being overlooked for the RB Salzburg job in 2012, having coached the reserve team, Kovac took over as national team boss for his native Croatia. Respect is hugely important in such a collective.

Treble-chasing Bayern face Bayer Leverkusen in the German Cup semi-final on Tuesday - and Real Madrid in the Champions League last four the following week.

Bayern was initially in talks with former Borussia Dortmund coach Thomas Tuchel, but he informed the club that he had agreed to take over another team while it was still trying to convince Heynckes to stay.

Real is looking to become the first club to win three straight European Cup titles since Bayern's hat trick between 1974 and 1976.
