Didn't join in with it, having one chant for two players is incredibly lame. Pretty sure Osvaldo and Ramirez were looking at the Saints fans in bemusement when it was being chanted.
If we really can't do anything too complicated (even though we had some cracking suggestions in that other thread) then at least do something we don't use, like "Osvaldo our lord" (Marian chant), or "Dani, Dani Osvaldo will score a goal for me" (Heartbeat/Maxi Rodriguez chant), or "Dani Osvaldo, Dani Osvaldo...running down the wing, hear Southampton sing, Dani Osvaldo".
