The German has hailed Juve's qualities as his Bayern side prepare for battle against them later tonight...
Both sides lock horns later tonight. Bayern are flying high in the group, while Juventus are playing catch-up. Rummenigge has hailed the strength and depth of the Bianconeri, and believes Diego can lead them to big trophies this year.
"Juventus have been built really well. I think they are capable of fighting for the Scudetto and doing really good in the Champions League," the German told Tuttosport.
"They are a reborn team after what happened in 2006 [Calciopoli]. This is a key game in the group, and expectations are high."
Bayern could have signed Diego from Werder Bremen, but they suddenly backed out of talks once they heard of Juve's interest in an attempt to keep relations between the two clubs harmonious.
"Diego's father contacted us about the player, but he told us that Juventus were in advanced talks," added Rummenigge.
"We met with them, but I got in touch with Juve to hear their version of the deal. After that, we pulled out as we did not want any problems."
