Manchester City boss Pep Guardiola visited Bayern Munich on Wednesday.
BILD says Guardiola arrived at the club's HQ just as Bayern coach Niko Kovac was taking training.
It's claimed the Catalan was just stopping by to say 'hello' and see some of his former directors and staff ahead of travelling to Barcelona.
Guardiola still owns an apartment in Munich.
Among those to greet their former coach were Bayern president Uli Hoeness and recently appointed sports director Hasan Salihamidzic.
