Billy Barr was left a frustrated man after his side suffered a narrow defeat to Derby County in Premier League 2
Barr's boys dominated for long spells, but fell to a 1-0 defeat against The Rams away from home.
A close contest between two hard-working sides was settled by Morgan Whittaker’s low strike four minutes before the break.
Richie Smallwood, Ryan Nyambe, Harry Chapman and Sam Hart all came into the side, at the expense of Sam Barnes, Lewis Thompson, Brad Lyons and Dominic Samuel, who made his long-awaited first team return late on against Luton Town at Ewood Park.
And speaking afterwards, Barr was downbeat after witnessing his side's display against The Rams.
“I thought the first half was the worst we’ve been since I took over and the lads all agreed that it was unacceptable," he admitted when reflecting on the encounter.
“We ended up changing the system at half time to a back three, partly because Joe Rankin-Costello had a little bit of a tight hamstring.
“We were camped in their half in the second half, but we didn’t test their goalkeeper enough.
“It’s disappointing, because we were trying to build on the performance against Tottenham a week earlier, where we kept the ball well, moved it well and scored some goals.
“But it’s gone now, we need to move on and learn from it.
“The first team players are ultimately the most important and there’s a reason why they’re playing. We set the standard against Tottenham, but we were not good enough against Derby."
