"I've played against many top players and in terms of age and that ability to create something, he's one of the best, if not the very best."

Despite the threat of Yamal and his strike partners Raphinha and Robert Lewandowski, who has been passed fit to play against Inter after missing Barça's last four games, the Serie A side are optimistic of reaching the final.

They have home advantage in the second leg and recovered from three defeats in a row to show they can match the LaLiga leaders in Barcelona last week.

"We are up against a strong team, we have had a taste of that first-hand in the first leg," Inzaghi added. "But I hope to see a great Inter against Barcelona. We know the importance of this game.

"It will take a huge performance. We need to be switched on and clearheaded. The group believes in their ability to win this game and can't wait for it.

"There's just the right amount of tension. It's almost a final and we get to play it in front of our fans."

Inter have no new injury concerns having made 10 changes for the weekend's 1-0 Serie A win against Verona, which kept them within three points of leaders Napoli, but they are sweating on the fitness of defender Benjamin Pavard and striker Lautaro Martínez.

Pavard has missed the last two games with an ankle issue, while Martínez went off at half-time in last week's draw with Barça.

"Pavard did part of the session [on Sunday] and the feelings were good," Inzaghi said. "Lautaro has been out for a week, so we will see how he is and see what decision we make tomorrow.

"With Lautaro, it will all depend on how he feels. But it will be difficult for a player to help us for 25 minutes if they're not ready to start the match."
