According to former midfielder Savio, Real Madrid must try to hamper Aguero.
Real Madrid were paired with Manchester City after qualifying for the last four by trouncing Wolfsburg.
Aguero has scored 18 goals in 25 Premier League games this season but has only netted two in the Champions League and missed a penalty in the second leg against PSG.
“I am a big fan of Aguero. He is one of the best attackers in Europe at the moment,” he told Omnisport. “He’s really clever and is always well positioned on the pitch.
“Aguero was superb in the two ties, he made the difference, despite missing the penalty kick. He is different from the rest. He is always dangerous and I believe that Madrid should take extra care with him.”
Savio admits he was impressed by City’s display in the 1-0 win over PSG at the Etihad Stadium this week and says Manuel Pellegrini should be given credit for his tactical approach.
“I was there watching PSG-Man City and Pellegrini was just brilliant with his tactics,” he said.
“They owned the midfield. Everyone always complained about the lack of balance in City’s game, their poor defending, but Pellegrini changed that. They were very clever in both ties. Fernando and Fernandinho did a great job protecting the midfield.”
