Arturo Vidal is one man who has been heavily linked with a move to the Bavarians, even more so after Heynckes was yesterday officially appointed as their new coach for next season, but Holzhauser says there is no risk of him or anybody else making the same trip.

"Jupp is far too loyal to take a player with him to his new club," he told the Bild newspaper.

"He would never do that."

Indeed, Heynckes is renowned for his loyalty and correctness having returned his company car with a full tank of petrol on the day that he was sacked as manager of Borussia Monchengladbach in 2007.

And Heynckes insists he will remain committed to Leverkusen until the end of the season, even though he knows that, by leading them into the Champions League, he risks leaving his future club out of the competition.

"I will put all of my efforts into reaching this great aim with Bayer," he told the Rheinische Post newspaper.

"That means direct qualification for the Champions League."

And given the job he did with Monchengladbach in 1987, it can be presumed that he will stick to his word.

Back then, after having announced that he would take over at Bayern for the first time in his career, he set a new club record of 10 consecutive victories to lift the Foals from 11th in the table to finish third.

Such a record in Leverkusen's last seven matches could yet see them win the Bundesliga title.

They currently trail league leaders Borussia Dortmund by seven points while they have the same advantage over Bayern, who lie fourth, two points adrift of third-placed Hannover and a place in the final qualifying round for the Champions League next season - their minimum aim.

Heynckes is one of five people to coach Bayern on more than one occasion.

Udo Lattek, Heynckes' predecessor in 1987, Franz Beckenbauer, Giovanni Trapattoni and Ottmar Hitzfeld have all returned to the Bayern bench for a second spell, although Heynckes will set a new record with next season being his third spell at the club.
