Pep Guardiola shuffled the cards at Bayern Munich as the treble winners beat his former club Barcelona 2-0 in a friendly on Wednesday.

The Spaniard, who won 14 of 19 possible titles in four years at Barcelona, made sweeping role changes as he works his way into the new job after the Bavarians won the Champions League and domestic league and Cup double last season under Jupp Heynckes.

"It was a special game for me," Guardiola said. "I was a Barcelona player and coach my entire life. Bayern have given me a very good team. I have nothing to complain about at the moment. My football is easy to understand."

Against a second-string Barcelona, missing their new coach, Gerardo Martino, and their big signing, Neymar, as well as the midfielders Xavi and Andrés Iniesta among others, Guardiola started the game without a striker.

Philipp Lahm was pushed forward into an offensive midfield role after years of playing as right-back and the recent signing and former Barcelona talent Thiago Alcântara moved straight into midfield.

The move paid off in the 15th minute when the diminutive Lahm, Bayern's captain, headed in a smooth Franck Ribéry cross.

"Barcelona were not complete but the win is still a boost in confidence," said the Frenchman Ribéry.

Bayern, who crushed Barcelona over two legs in the Champions League semi-final last season, were the sharper team in the first half, with their impressive depth in the squad on full display. Lionel Messi came close in the opening seconds with a sizzling shot but Barça's captain was otherwise shut out.

With both teams still in pre-season training, the coaches made many changes in the second half with the game losing its pace and edge.

The forward Mario Mandzukic, who came on as a substitute, added another goal late in the game, tapping in from close range.

On Tuesday, Barcelona hired the Argentinian Gerardo Martino, known as a disciple of the club's possession-based style that Guardiola applied successfully, to replace Tito Vilanova. Vilanova, 44, stepped down last Friday to continue treatment for throat cancer after leading Barça to the La Liga title in his first season since taking over from Guardiola.
