Perisic left Inter for Spurs in a free transfer.
He has won titles in both Italy and Germany and formed part of the Croatian team who reached the 2018 World Cup final, although Olic suggests the idea of plying his trade in the Premier League was a “weak point" for the player.
“Honestly, I was a little surprised that he went to England. He had a great season at Inter and I expected him to stay," he told Perform.
“Ivan has played in Germany, France and Italy in recent years. But we said that England have always been a weak point for him. It's clear that he sees the Premier League as a challenge.
“He knows the manager, his technical staff and his game system. I don't think he will have problems adapting to the new league."
