West Brom midfielder James Morrison expects to face a West Ham side keen to impress their new boss this weekend.
The Hammers confirmed on Thursday that Gianfranco Zola will succeed Alan Curbishley in the Upton Park hot-seat, although he will not take charge of his new side until next week.
He will, however, be an interested spectator at the Hawthorns on Saturday, keen to run the rule over his inherited squad.
As such, the Baggies are aware the challenge facing them has become even tougher.
"You do wonder what condition the West Ham players are going to be in," said Morrison.
"With a new manager coming in they will be fighting for their places and trying to impress Zola.
"We have to be on the top of our game and keep doing what we have been doing and hopefully get the all-important break to give us a win."
Despite Albion only having a solitary point to show for their endeavours three games into their Premier League return, Morrison insists results have not reflected their performances.
He added: "We have come off the field in our first few games disappointed that we haven't got our first win of the season.
"We have been working hard in training and hopefully we can get a fluke goal to set us on our way and off and running.
"Last season we had a few off form games. But in the Premiership you cannot afford not to be right on top of your game. We have got to concentrate for 90 minutes.
"The manager realises the problems and we are working on them in training."
One of the Baggies' biggest problems has been a lack of goals, with their only strike so far coming from the penalty spot.
However, Morrison insists the club have the firepower to compete in the top flight and is backing those charged with the task of providing a cutting edge to come good.
"I think everyone has got to get a few goals to keep the pressure off the strikers," he said.
"They have had chances and if they keep getting into a goalscoring position then the goals will come. I have no doubt about that.
"Ishmael Miller and Roman Bednar have been staying behind after training to put in more work so it is obviously playing on their minds at the moment. I am sure they are trying to put it right."
