Roberto Martinez says he does not agree with Thibaut Courtois' comments about playing in Russia.
The Chelsea goalkeeper indicated that it was a massive effort for the Belgium national team to travel to Sochi for a friendly against 2018 World Cup hosts Russia.
Ahead of Tuesday night's friendly, Courtois had said: "There are so many beautiful opponents available.
"Germany, France, England, Netherlands…you name it.
"And we go to Russia…"
Courtois has since been ruled out with a hip injury and returned to London for treatment but Martinez touched on his comments and insisted that a player needs to undergo all sorts of tests to prepare themselves for all types of football.
"Players sometimes think differently than a coach," said MartÃnez.
"Friendlies are currently regulated in a period which is very important for clubs. I have as club coach experience how players bring international success to their club, but after a negative experience can a player need a few days to get back on it.
"If you want to play with your national team and in big tournaments, however, you must be able to deal with it."
