West Ham boss Manuel Pellegrini was pleased with Samir Nasri's performance for victory over Arsenal.
Declan Rice proved West Ham's matchwinner on the day.
Nasri made an encouraging Premier League debut too, lessening a headache Pellegrini had in the midfield area.
“He kept with the pace [of the game] for the 65 minutes. I think he could have continued, but I didn't want to take the risk.
“He gave us what we need as a team, because in that position, with Lanzini's injury, Yarmolenko's injury, we needed him. I was sure that if Samir wanted to be the player he was before he would do it."
