Steve Bruce says he will ring the changes at West Bromwich Albion after an embarrassing loss to Luton Town.
The Baggies must bounce immediately against Middlesbrough on Tuesday as their promotion hopes hang by a thread.
"I'm hoping we've bottomed out," Bruce said.
"I'm looking for a response and maybe I look around at other people and say 'right, it's somebody else's chance.'
"The reason I have come in from afar is to work with good players. It's okay looking a good player on paper – you've got to show it on the pitch.
"Now is the time where we have to show our metal.
"A lot of these players played in the Premier League last year. But that means nothing when you come to Luton Town who are fighting away in the Championship.
"You have got to make a fist of it. You have got to have more about you than what we have shown."
