Manuel Pellegrini believes Marko Arnautovic is "happy" at West Ham United despite reports accompanying him with a move and urging the Austrian to prove him with his performance.
Arnautovic told Austrian weekly Kurier last week he wants to "compete with the best," while his brother and agent Danijel said that 29 years of age must "play for a top team" to fulfill their potential.
Manager Pellegrini said he understood the player's ambition but was confident in his commitment to the London club.
"I know Marko, I know how he thinks," the Chilean reporter said.
"I think every player in each team must have an ambitious mind and wants to further improve their career.
"But I'm sure he's happy here and that the best way to look is to continue to perform well."
Arnautovic, who joined the club in Stoke City in July 2017, contributed five goals to West Ham this season, but a recurring knee injury has kept him a limited training schedule for most of the campaign.
"Marko had a difficult season to do," Pellegrini said before his Saturday home match against his former Manchester City club.
"He has not been able to work a full week from the beginning because of his knee, but in those two weeks he has had no problem.
"I expect him to give his maximum performance in every match, he has a lot of power and goals and I expect to make a full season as he did for half a season last year."
