The West Ham United forward has been heavily linked with an exit this month.
West Ham boss Manuel Pellegrini spoke to reporters after his side's victory over Arsenal today, and shared the reason why he brought Marko Arnautovic off with 20 minutes still to go, as quoted by Football.London.
The 29-year-old has been in the headlines over the past couple of days, with reported interest in his signature from the Chinese Super League.
His brother and agent claimed on Thursday that the Austrian was keen to leave the Hammers, and if he does really want to go, it will be incredibly hard for the east London outfit to keep hold of him.
Arnie certainly didn't seem to be himself against Arsenal today, and West Ham boss Pellegrini responded to reporters when asked why he chose to substitute the forward after 71 minutes, as quoted by Football.London:
"Marko felt the same pain in his back as he felt during the Cup so it was not good for him to take the risk to continue. He was part of the team and the complete team played well. Everyone can understand what you want to think but we are just seeing what happened in the game and not another issue."
Arnautovic would earn incredible amounts of money if he did move to China, but the 29-year-old is currently in the midst of his prime years, so moving away from the Premier League would surely be the easy option.
There are still three weeks remaining until the January transfer window slams shut, and judging by the Austrian's reaction to being substituted, it seems as though the West Ham fans might not see him at the London Stadium again.
