The Bavarians were paired with Guardiola's former club in Friday's draw for the Champions League semi-finals but the 65-year-old feels the legendary Dutchman would be able to offer more information about Barca.

"Out of respect for his old club Pep can't give away any details about Barcelona, but I don't need him to," Heynckes told reporters.

"I know Spanish football well and I know Barcelona well. If I wanted to call anyone I would choose Cruyff, because he invented Barca's style of play."

Cruyff made 143 appearances for Barca as a player from 1973 until 1978 and was their head coach from 1988 to 1996.
