Recapping Real Madrid's matches

I'm wondering if Real Madrid has faced Olympiacos, Panathinaikos, AEK Athens, and Aris in European Cup history. They definitely played Olympiacos in the 1997-98 Champions League, winning 5-1 at Bernabeu, but I think the away match ended 0-0. Then in 2007-08, they won 4-2 at home but lost away. Against Panathinaikos, Madrid lost 1-0 in Athens and won 3-0 at home. With AEK Athens, they drew 3-3 and 2-2 in the group stage. Some details are a bit fuzzy.Reviewing Real Madrid's away results in Greece

I'm trying to compile Real Madrid's away match results in Greece. The user mentioned "2 draws and 5 losses," suggesting they haven't secured an away win against Greek teams, which would imply 7 matches without a win. But I need to clarify this further. I can't recall specific matches in the 1970s or 1980s, and I'd prefer not to assert incorrect facts. Last match I remember was against Olympiacos in the 2007/08 season; I think they might have lost that one. Checking if that stat is still true could be valuable!
