When Bayern Munich coach Jupp Heynckes passes on the torch to Pep Guardiola this summer, the veteran trainer will leave enormous shoes for the Spaniard to fill.
Heynckes' Bayern have broken record after record in the Bundesliga this season and are on pace to win a treble.
Especially given that the Bavarians recently hammered the very Barcelona that Guardiola built by a 7-0 margin in the Champions League, it's very much uncertain whether the incoming trainer will be able to keep Bayern at their current level. But the Bavarians made their decision in January to pursue Guardiola without considering renewing Heynckes' deal.
It's not just the possible level of success that may differ between Bayern under Heynckes and Guardiola, but the the entire way the club operates.
It's unknown exactly how the incoming trainer intends to play, and he certainly will join Bayern older and wiser than he was when he left Barcelona last summer. But based on his previous tenure, he is likely to bring a whole new set of strengths and weaknesses to the club.
