“Juve have a great project in place and they just keep going. Every year they try to get stronger,” Lukaku told La Gazzetta dello Sport.
“Without doubt, Juve are one of the two-three best teams in Europe. They’ve got a great Coach on the bench and extraordinary players in every area of the team.
“Cristiano Ronaldo stands out, but watch out for the others too. Paulo Dybala is already impressive and getting stronger, while I love Douglas Costa. He’s an exceptional signing and his career shows he always makes the difference.
“It’s a tough group, but obviously Manchester United want to finish on top.”
Lukaku’s brother Jordan plays for Lazio as a wing-back, so Romelu was asked if he’d enjoy a Serie A experience.
“Why not? I hope it happens.”
