told Reuters newspaper Kurier that he”needs to compete with the very best”.
Agent Danijel Arnautovic stated his brother needs to”play for a top team” and it was”possible” he could depart.
“He’s happy here. Every player wants to play with the biggest team, but I don’t think he is thinking about that, but only around West Ham.”
The 31-year-old is training with the club in an effort to secure a permanent deal.
He had been due to have a medical as he reaches the end of an 18-month doping ban, but concerns have been expressed over his fitness levels.
“We will see about Nasri,” added Pellegrini. “He’s working with us after a long time with his own ban. We’re currently giving a hand to return to soccer to him.
“I hope he is going to be fit between today and the end of the year and if he is we will attempt to sign him.”
