Damien Johnson was left "disappointed" after his side bowed out of the Premier League Cup at the quarter-finals stage, with Everton earning progress at Goodison Park.
A first half spot kick from Bassala Sambou just four minutes into the encounter handed Rovers the start they didn't want, before Josh Bowler made it 2-0 midway through the first half.
Although Rovers did pull a goal back through Harry Chapman after the interval, it wasn't enough.
And speaking afterwards, a downbeat Johnson felt his side didn't show their true colours on the night in Merseyside.
“I'm pretty disappointed, to say the least. I don't think we showed up in the first half," the Under-23s chief reflected.
“All the things we've done well recently, we were the opposite, certainly in the first half.
“We spoke about how Everton like to play and what they like to do, and the message was to not give them any opportunities to set traps.
“The way we started the game was really disappointing. As good as we were against Manchester City last week, we fell well below the standards we set ourselves as a group at Everton.
“Some of the players fell below the standards they set themselves. We did okay in the second half, but the damage was already done in the first half.
“I don't know whether the early penalty unsettled us or not, but we never really got going. I'm disappointed.
“We knew we had the quality at the top end of the pitch to cause them problems, but at the other end we gave ourselves a mountain to climb.”
