After knocking out Juventus in the last 16 and beating Bayern Munich in the quarter-finals, the 50-year-old coach believes his team no longer have the element of surprise in their bid to reach their first Champions League final.

"They are wise and now they know who we are. They know that the tie is going to be difficult and they will be prepared, no doubt about it," Emery said.

"But it is inevitable for them to feel as the favourites, as it is normal, their potential is massive. But we have greater motivation and enthusiasm."
