The veteran trainer is relishing Wednesday's visit of the Spanish outfit, and insists his side are only focused on surviving the group stage of the Champions League
The Bavarians' coach is aware that Los Che are among the top teams in Spain, but believes his side have more than enough quality to come out victorious in Wednesday's encounter at the Allianz Arena.
"We go into tomorrow's game high on confidence," Heynckes told reporters. "It really seems we have added quality to our squad over the summer and it is good to have alternatives on the bench – that will be important for the rest of the season.
"Valencia are among the top three in Spain – just remember 2000 and 2001 [when they twice finished Champions League runners-up].
"The team of today is very well organised and physically strong. Their pressing is great and I have a lot of respect for them."
Heynckes then went onto say that Bayern are no longer thinking about last season's loss against Chelsea in the final of the elite club tournament, and instead are focused on surviving the group stage.
"We no longer linger on our final defeat [by Chelsea]. This is a new season and we have to concentrate on our group now – everything else is just hypothetical," the former Real Madrid boss added.
"The past is the past and I do not think about it anymore. It is not relevant to talk about the Champions League final in London either. We have to survive the group and then we will see."
Bayern's clash with Valencia kicks off at 20:45CET.
