BURTON Albion will look at a new set of trialists this week after allowing three of the current batch to leave the Pirelli Stadium.
Striker Thomas Verheydt, defender Louis Cutajar and goalkeeper Joe Anyon have all played in both of Albion's pre-season matches so far, but all three have now left the club ahead of tonight's trip to Hednesford Town (7.45pm).
Brought in from Holland, Verheydt was an imposing physical presence but was short of match fitness and the gap between the Dutch amateur leagues in which he was playing and League Two could have proved too great for the 22-year-old.
"We were really grateful to be able to have a look at Thomas," said Rowett.
"It's been difficult for him as he's come from an amateur league and hadn't trained at all before last week.
"We had a look at him in two games and just felt he wasn't quite where we wanted him to be in terms of mobility, so we've let him go back to Holland.
"The gauge is the strikers who played against Sheffield United on Saturday, and if they're not up to that standard, there's no point wasting their time."
Left-back Cutajar looked solid defensively and got himself on the scoresheet against the Blades, but even with Damien McCrory injured, Albion have plenty of options in his position.
"He took his goal very well but we're looking for that bit extra," said Rowett.
"He could be a useful back-up but that's not really what we're looking for."
Albion are seeking a goalkeeper but Anyon has other options and Rowett wants to try other players in that position as he seeks competition for Dean Lyness.
"Joe hasn't had too much to do, so you're looking at other things in that case," said the Brewers chief.
"He has gone to another club on trial as we can't offer him anything at the moment.
"What we've got to do is move on quite quickly.
"If there's any we don't think are quite up to speed and aren't going to give us what we want, we've got to move on and have a look at another two or three," he said.
"It's the ruthless nature of this time of the season.
"Sometimes you might have to make decisions which might not turn out to be the right ones overall because it's difficult when you only have a week.
"But you go with your gut reaction and make a choice."
Christian Ribiero and Jordan Cranston, who both featured in the second half of Saturday's Bass Charity Vase tie, will be kept on for the midweek games against Hednesford Town and Mickleover Sports, tonight and tomorrow night respectively.
"All you're looking for is little bits so you know if they're worth keeping for another week," said Rowett.
"With Christian, you can see that going forward, he's very athletic and very comfortable on the ball. He's played 50 times in the Championship for Bristol City so he's a good player."
On Cranston, recently released by Wolves, Rowett said: "Jordan showed some good bits – good athleticism, good size, good attitude – so he's worth having a look at again," said Rowett.
"It's never easy – he has never met the lads before, he's turned up at 1.30pm for the game and he's got to play 45 minutes. I thought one or two things he did were quite bright."
