The Hammers have struggled to get points on the board this season and have managed only three from their opening six Premier League games.
The West London club currently sit in the relegation zone, and Wright believes that the Croatian manager has a lot of technical work on his hands following a successful debut season in East London.
“But right now he's got a lot of technical work on his hands to get them back on their axis. I'm sure he'll do so, but it's not going to be easy.
“At the moment it's as though the fans – and everyone knows Upton Park was more intimidating than most stadiums – are just waiting for things to go wrong.
“The atmosphere just isn't there and it's up to the team to start cutting out the mistakes and start producing the magic.
“It's going to be a long old campaign if they don't do it soon."
