Roma will face Manchester United in the Champions League quarter-finals.
Spalletti said: “The dual between Ronaldo and Mancini will be fascinating.
“They both have speed, technique and invention.
“Ronaldo showed what he could do with that run down the left to cross for Henrik Larsson’s goal against Lille.
“But Mancini stole the show with the second goal against Lyon, so you’d say he’s ahead of Ronaldo right now.
“Liverpool were the ones who did really well in the last round. Manchester struggled a bit.”
