Arsenal fullback Kieran Tierney says Gabriel Martinelli is destined to be "world class".
In a Reddit Q&A, Tierney was asked who could be a world beater in the future.
"Again, I would say Martinelli," Tierney replied.
"I think his hunger and drive and his talent together as one is more than enough to be a world class player for many years."
On moving south from Celtic, he added: "I didn't move to Arsenal to live in London. I came here to London so I could play for Arsenal."
