Diego Maradona would like to watch how Pep Guardiola trains his Bayern Munich team and said the freshly-crowned Bundesliga champions would be unbeatable if they had Lionel Messi as well.

“I would like to work for a week with Guardiola to watch him in training. I would be very happy to visit Bayern Munich,” the former Argentina star player and coach, Maradona, told Wednesday’s edition of German weekly Sport Bild.

The 53-year-old said that the Bundesliga has reached the same level as the Spanish Liga and believes that Guardiola “sensed this development early and is now utilising it at Bayern.”

Munich won the treble last season and on Tuesday clinched the 2014 league title in record time with seven games to spare. Maradona singled out Bayern and Germany captain Philipp Lahm, saying that he “makes the difference.”

Maradona, whose national team coaching career ended after a 4-0 quarterfinal defeat against Germany at the 2010 World Cup, said the Bayern team will be “perfect” once Polish striker Robert Lewandowski arrives in the summer from Borussia Dortmund.

He added that only one player could top that up, compatriot Messi, whom Guardiola coached during his term at Barcelona, in an all-but-unlikely scenario of going to Munich as well. “Lewandowski and Messi? Then everyone else would play for second place. In every competition, in every league,” he said.

“And if Bayern buy Messi I will become Guardiola’s assistant coach.”
