Former Juventus and Inter Milan star Roberto Boninsegna rates Romelu Lukaku ahead of Cristiano Ronaldo.

Ahead of this weekend's huge game, Ronaldo enters the duel with 19 goals in 18 games played this season, while Lukaku has 17 goals in 22 games.

Boninsegna said, "The only Inter player who put Fiorentina's defence in difficulties was Romelu Lukaku, who had just returned.

"Beautiful couple, Lukaku and Cristiano Ronaldo.

"For Inter, I think Lukaku is a more decisive player. Irreplaceable. Cristiano Ronaldo was a great player, but he seems a bit decadent to me."
