Newcastle fullback Kieran Trippier is confident Sandro Tonali will be a Toon star.
The midfielder faced his old club AC Milan for this week's Champions League 0-0 draw in Italy this week.
Trippier said after the game: "Sandro is absolutely quality and brings a lot of quality to our team.
"I played against him many times before and knew it was an emotional occasion for him to come back to Milan this week. He spent so many years here and it was good for him to come back.
"But he's a top player with huge potential."
