West Ham striker Sebastien Haller expects a battle today against Manchester City.

The Irons open the season against the champions.

Haller told the club's website: "There are better games to build your confidence, I think. Hopefully I will touch the ball. We will see.

“What can I say? Everyone needs to be prepared for this game because it's City. The champions from the Premier League, the FA Cup, and even the Cup that I don't know the name of!

“So yes, it will be difficult. From the first game we will need to make a crazy game. I think it is probably best for the team to get a game like that because we will need to be focused 100 per cent. We don't have any choice."
