Bayern's Jupp Heynckes, 68 and at the twilight of his career, is chasing a second Champions League crown and unprecedented treble for a German club in what looks to be his last professional season with Pep Guardiola taking over in July.

Heynckes' side ran away with the German title this term and in Europe have recovered superbly from the bitter disappointment of losing last year's final to Chelsea at their home ground.
Nicknamed Osram after the German lightbulb manufacturer for the way his face reddens when agitated, Heynckes otherwise rarely displays his emotions unlike Dortmund boss Jurgen Klopp, whose volcanic explosions on the sidelines are common.
The 45-year-old could not be more different in both origin and his approach to the game.
The fair-haired Klopp, who spent most of his playing days at Mainz 05 in the second division, is at the start of what could be a glittering coaching career.
While Heynckes is probably signing off from the game, Klopp is only just making his name on the world stage having created a young and exciting outfit despite financial restrictions at Dortmund since their near bankruptcy in 2005.
What he may lack in international experience he makes up for in exuberance and a smart tactical game plan is reflected in Dortmund's offensive style of play which helped them to the Bundesliga titles in 2011 and 2012.
TREBLE HOPES
Heynckes, a member of Germany's all-conquering national team of the 1970s, is a product of a philosophy based on discipline, hard work and a constant strive for excellence.
A world-class striker who won the 1972 European Championship and the World Cup two years later with Bayern president Uli Hoeness, Heynckes was schooled as a coach at his home club of Borussia Monchengladbach, where he also enjoyed huge success as a player.
He joined Bayern Munich in 1987, coaching them to two consecutive league titles in his first spell at the club.
After leaving Bayern, Heynckes went on to spend nearly a decade in Spain where he also enjoyed a 1998 Champions League victory with Real Madrid.
His third stint at Bayern, after a brief spell in 2009, could prove to be his most successful with his team also in the German Cup final against VfB Stuttgart on June 1.
Heynckes, a master in managing big-name players, also excelled in rotation this season with a bigger squad after several buys last year boosted his options considerably.
New signings Dante, a central defender, holding midfielder Javi Martinez and striker Mario Mandzukic all grabbed starting spots instantly while established players such as Arjen Robben and Mario Gomez were kept hungry and often on the bench as they constantly had to prove their worth.
