LONDON: Inspired by Bukayo Saka, Arsenal scored five goals in a wild first half at West Ham before settling for a 5-2 win that lifted the team into second place in the English Premier League in its bid to chase down Liverpool. Saka was one of five different scorers for Arsenal at the Olympic Stadium on Saturday and also had a hand in three goals, by Gabriel, Leandro Trossard and Martin Odegaard. Kai Havertz netted the other goal for Arsenal in its biggest league victory this season.
