Former Arsenal boss Arsene Wenger is adamant Aaron Ramsey will make a big impact at Juventus.
The Wales midfielder will move to Juve on a Bosman deal in June.
Wenger said, "It is a great step because he is an excellent player.
"There are few midfielders with his qualities, because he can also assert himself in an attacking way and can make goals. He is a very complete midfielder, someone who can be anywhere on the field during a match.
"His departure is a great loss for Arsenal, while he is taking on a very interesting challenge at Juventus."
