Hungarian hopes team-mates will be prepared for a hard fought encounter...
The Hammers endured a difficult start to the season and fell to the bottom of the table, but recently registered their first league victory by beating Tottenham.
Now the Hungarian says it will be a difficult test against the east London club when the Cottagers play them on Saturday.
"They have a new manager and some new players and I think they need time. It’s going to be a tough game for us, no question," Gera told the club's official website.
"They have very good individual players and if they’re playing well, it’s difficult to play against them.
"Looking at the table, Everton started badly but Everton are a very good team. West Ham, I think, are in the same situation. They struggled with the start but I’m sure they will be a much better team than the table shows at the moment.
"It’s very important to start well against them and frustrate the home crowd. We want to win this game; there is no question about that. We want to be better then the last few years away from home. Hopefully the players will be ready for this."
