West Ham boss Manuel Pellegrini has warned fans not to expect too much too soon from his new-look team.
The Hammers meet Arsenal on Saturday.
“I don't know if finding my best XI is closer or not because we need time for a lot of reasons," the 65-year-old said.
“If you review my career - at Villarreal, at Malaga, in Manchester - the first games that I managed were never good games.
“I remember in Manchester we lost our first three games away or rather lost two and won one so I'm not worried about that. But as soon as we can win it would be better."
