Aaron Mooy has described a year battling relegation in the English Premier League as feeling like being "on drugs", suggesting the emotional cost of each result proved far more exhausting than his heavy load of games.

While Mooy has probably never experienced such intoxication, he says the mental rollercoaster on the journey of survival with Huddersfield felt like a close experience.

Finding a balance between the euphoric highs and despondent lows was not easy for Mooy, who was unaccustomed to the pressures of the Premier League and the heavy burden of expectation.

"It’s really dramatic. If you lose against a team around you it’s the end of the world," the Socceroos midfielder said at Australia's World Cup training camp in Turkey.
