His pupil bettered the Dutch master when Jose Mourinho's Inter Milan strolled to a comfortable 2-0 victory in the Champions League final over a weak Bayern Munich team coached by his one-time boss Louis van Gaal.
Argentina's Diego Milito scored twice yesterday as Inter Milan squeezed the life out of a hesitant Bayern team to end a 45-year wait for its third title.
The victory might also signal Mourinho's exit from Inter. After the game, he said it was "more probable that I'll go than stay." He is tipped to take over at Real Madrid, where yesterday's final was played.
The Argentina striker Milito scored in the 35th and 70th minutes at the Bernabeu Stadium to add the title to Inter's triumphs back in 1964 and '65.
The merited victory - Inter dominated the game - meant that Inter coach Jose Mourinho completed the triple triumphs of the Champions League and domestic league and cup successes and became only the third coach to win the title with two different clubs.
Mourinho, who won it with FC Porto in 2004, out-thought Bayern coach Louis van Gaal, the man he worked for while they were at Barcelona. This time the pupil was the master as Mourinho relied on his solid defense to snuff out the threat of Bayern's Arjen Robben and expertly won the game on the counter-attack.
Milito's two goals were taken with style and he had great support from attacking midfielder Wesley Sneijder and defensive midfielders Esteban Cambiasso and Javier Zanetti, the Inter captain who collected the trophy in his 700th appearance for the club.
The loss meant that Bayern missed out on the treble, having also won the domestic league and cups.
"We were not good enough to impose our game," Van Gaal said. "Inter only reacted but they still won deservedly. The timing of the goals was decisive. The players learned today that it comes down to small details.
"I still have the feeling that we could have won. There was no great difference. We attacked, Inter defended. But you have to be in great shape to beat Inter and we were not today. I still think Inter merited the win."
Franz Beckenbauer, honorary president of Bayern, said Inter deserved its victory."Bayern did not have its day. We had a few moments at the start of the second half but that was not enough," he said. "They made fewer mistakes."
After the final whistle, Mourinho walked onto the field and was congratulated by his players in a low-key celebration by his standards. In the past he has been known to race across the pitch to celebrate some of his most famous victories, infuriating opposing supporters.
