Bayern Munich boss Jupp Heynckes has praised the attitude of both his players and staff for their efforts in recent weeks, on his return to Bavaria during the early stages of his third spell with the club.
Speaking to the Club's official website, Heynckes has lauded the exertions of everyone involved with Die Roten, with Bayern are now afforded a two-week break with the current international break.
The Bayern boss told fcbayern.com: "We've gone through very demanding changes, of course it's had an effect on the players."
After Carlo Ancelotti was sacked following Bayern's 3-0 loss to Paris Saint-Germain in September, Heynckes returned to the club having taken charge of the Bavarians in 1987 for four years until 1991 and then again more recently between 2011 and 2013.
The 72-year-old former Hannover 96 and Borussia Monchengladbach forward has taken the German side to three league titles - two back to back between 1988 and 1990 - as well as three DFL Supercups.
His most impressive feat was during the last season of his second spell in charge, as he led Bayern to a treble of DFB Pokal, Bundesliga and UEFA Champions League in 2013, beating fierce rivals Borussia Dortmund in that year's final at Wembley Stadium.
Arjen Robben, who scored the winner for his side in that game, has been instrumental in his returning steward's almost-seamless transition back into the fold and on his team-mates efforts recently, was equally glowing.
"We could have substituted four or five more players", said the Dutchman. "We were all exhausted.
"What we've turned in over the last few matches is madness."
Returning to take up the reins once more, Heynckes has overseen a seven-game unbeaten run, including beating RB Leipzig on penalties at the end of last month in the German DFB Cup.
The Bayern boss is quick to sing the praises of not only his men on the pitch, but the hard work that has gone on behind the scenes also, with particular reference to the club's physios and medical staff.
"They've worked with the players day and night."
