Current Bayern Munich boss Jupp Heynckes has stated that the job of Real Madrid trainer is a very difficult position because of the immense pressure.
The German was in charge of the Spanish capital club in 1997-98 and helped Los Blancos to Champions League glory, before getting the sack due to disappointing domestic results.
"Real Madrid's a difficult place to work in the long-term. There you have to win, win, win, play with attacking style, keep the local media on board, and have a good relationship with the president," Heynckes was quoted as saying by Soccernet.
"That's a lot of ifs and buts and, as we only finished fourth in the league, I had to pay the price."
Heynckes then looked ahead to the upcoming Champions League semi-final against Madrid, and stressed that it's not about personal revenge for him.
"For me this tie is not in any sense a matter of personal revenge. I had the honour of being Real's coach in 1997-98 and was lucky enough to lead them to victory in the Champions League.
"Naturally I was very disappointed that the final against Juventus turned out to be my last game in charge, but that's football, that's Real."
The first leg of the Champions League semi-final between Bayern and Madrid takes place at the Allianz Arena on Tuesday evening, and kicks off at 20.45CET.
