Bayern Munich coach Jupp Heynckes has made it clear that he would prefer Johan Cruyff's advice over that of Pep Guardiola.
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.
