Marko Arnautovic has admitted that he underestimated the Chinese Super League prior to him joining Shanghai SIPG.
The Austria international made the move to the Far East last July in a £32million transfer from West Ham.
It was a surprising deal for many due to the fact that the forward had been linked with the likes of Manchester United not too long before.
But many believed he decided to concentrate on a big pay day by moving to China, rather than staying in the Premier League to fight in a more well established league.
And Arnautovic has admitted that his standards slipped not long after making the move to Shanghai.
As reported by Beanyman Sports , the 31-uear-old said: "I underestimated it. I didn't train. I didn't look after my body. I was eating. I was drinking fizzy drinks - Sprite, Coca Cola, Fanta - all these sugar drinks that are not good for the body.
"Eating at wrong times. Not sleeping, because when I came to China it took me about three weeks until I could adapt to the time. I went to bed at 6, 7 o'clock in the morning.
“I woke up 3, 4 o'clock in the afternoon, went to training, stayed up again all night, eating at wrong times."
Arnautovic went AWOL at West Ham to try and force through a move to China and managed to get his transfer six months later.
Doing so is believed to have increased his salary from around £130,000 per week to one worth over £10million a year for Shanghai.
So far the former Stoke man has netted 14 goals in 23 appearances and has now changed his approach to playing after careful consideration.
"This is exactly what I said before," he added. "Now I just put in my mind the club wanted me to come, to do well, to play for the title, and I changed because I need to do better and I need to be better. Otherwise you can't play here."
His contract with the club is set to run until December 2022 and so he is unlikely to be returning to the Premier League any time soon.
