West Ham United manager Slaven Bilic has admitted that he is "concerned" by his team's start to the season.

The Hammers, who moved into the London Stadium in the summer, have lost four of their Premier League games, winning just one, which was a 1-0 victory over Bournemouth in August.

Bilic's side sit in the relegation zone on just three points, but the Croatian believes that his team can go on a positive run if they get a result against Middlesbrough at home this weekend.

"I am concerned and it has been a bad start, but with one win we can build everything back with a win over Middlesbrough on Saturday," Bilic told reporters in this morning's press conference.

"I am asking myself a lot of questions even when it was good last season. You think about how you can change things. You can't sit still."

West Ham have won three of their six games at home in all competitions this season.
