Arsenal boss Arsene Wenger says he doesn't make signings based on talent alone.
The Frenchman says a mix of factors, including upbringing and education, are behind whether or not a deal is completed.
He told arsenal.com: "First of all you have to look at the level of education of the player because they have to learn the language.
"You have to look at their family's history and whether they've ever moved somewhere else, the culture and where the player's grown up.
"You hear that he doesn't like to leave home, things like that. I believe it's very important because not everybody is exportable without being negative.
"It's not necessarily a quality to go to a different country because the target in life is to be happy and some people are happier when they are in their own environment.
"Some people have that desire to discover other cultures, other places and people, and they will be more happy, so you have to analyse that."
