Greece international Christos Tzolis has joined Norwich City from PAOK on a five-year deal for an undisclosed fee.
The winger, 19, registered 16 goals and 10 assists across 46 appearances in all competitions last season as PAOK won the Greek Cup and finished second in the country's Super League.
He has eight Greece caps, having made his international debut last October.
"From the first moment, I was really excited to come here," Tzolis told Norwich's website.
"I said to my agent to sign as fast as possible here. It's a very good step for me.
