The Bayern boss has reacted angrily to suggestions that he might enlist the help of the former Barcelona and future Bayern boss ahead of his side's clash with the Blaugrana.
The former Blaugrana boss will take over the reins at the Allianz Arena in the summer and has as much knowledge of Barcelona as anyone, but Heynckes has claimed that anyone who believes he would give his successor a call of being disrespectful.
"Please respect me and my work," Heynckes told reporters. "I have never consulted anyone!"
Looking ahead to the tie, Heynckes said that he is expecting two great games against a team whom he knows well.
"We'll see two very entertaining games. Both teams like to attack and have a solid defense with good tactical awareness," Heynckes said. "I said before the Juventus game that I don't think playing the first leg at home is a disadvantage. Camp Nou is certainly a special stadium and we can expect a fantastic atmosphere there.
"I know Spain football very well, because I've always been interested in it, even after I left Spain."
While Bayern Munich is has proven to be as deep and balanced a team as there is in Europe, Heynckes is not overlooking the overal quality that Barcelona boasts despite Lionel Messi earning the lion's share of the plaudits.
"Barcelona aren't just [Lionel] Messi," Heynckes said. "They have great players like Xavi [Andres] Iniesta, [Sergio] Busquets, [Cesc] Fabregas and [David] Villa."
