Kovac is a reactive coach who has started with no fewer than seven different formations in his 30 Bundesliga games this term - something that should appeal to Bayern given the sheer breadth and depth of abilities in their squad; but the Berlin-born former Croatia worldwide still has certain predilections.

Frankfurt's head coach Niko Kovac.
After former Dortmund coach Thomas Tuchel rejected an offer, announcing he will join a big European club overseas.
"We're very happy that we could win Niko Kovac as a new coach for Bayern", sports director Hasan Salihamidzic said. "Bayern have thought of themselves and not for a second about Eintracht Frankfurt". "One has to accept that, but it's not a problem for us".
The club's resurgence has continued this term with Kovac's men fifth in the Bundesliga, just two points behind Bayer Leverkusen, who occupy the final Champions League qualifying spot.
Lewandowksi came off the bench to get on the scoresheet himself, his 27th Bundesliga goal of the season taken well in the closing stages as Bayern racked up a 15th league win from their last 17 outings.

In recent weeks, Hoffenheim manager Julian Nagelsmann's name has been thrown into the hat for the Bayern Munich job, especially following Thomas Tuchel turning the role down.
"It's not so simple, I have to admit", Kovac said.
But now the dream of managing Bayern is over, for the time being at least.
