Brighton manager Gus Poyet will this week attempt to get his new signings up to speed.
David Lopez, Dean Hammond, Stephen Dobbie and Andrea Orlandi joined Albion before the transfer deadline and could make their debuts against Sheffield Wednesday on Friday.
"They are fit. They just need match fitness," Poyet told the Argus.
"We did plenty of fitness tests with them last week and they are good but they need to play games. We are going to manage that during the week.
"We have done a little bit of 11 v 11 against the development group already. We are taking care of that.
"They look quite fit despite not playing, to be fair, but players normally are."
