Jarrod Bowen continued his fine start to the season to help West Ham to a victory at Luton that puts them top of the Premier League.
After dominating possession throughout the first half, West Ham found the breakthrough shortly before half-time when Lucas Paqueta's tantalising cross was headed in by Bowen, although Luton goalkeeper Thomas Kaminski may feel he should have done better as he parried the shot over the line.
Luton, despite being without the ball for long periods, did pose a threat on the counter and they carved out eight chances in the opening 45 minutes.
