Record signing Sebastien Haller believes that West Ham's opening Premier League victory at Watford can "launch" their season
"Sebastien Haller's goals were two very important goals for him," Pellegrini said.
"Coming to the Premier League is not easy. He had just one start in a difficult game against Man City, for a striker the most important thing is to score."
