Coventry City U21's coach Darren Murray admitted his frustration after his side's 2-1 defeat to Crewe.
City were a goal up at the break but conceded twince in the second half and speaking about this to Keiran Crowley, Murray said: "The first-half was as good as we've played all season in terms of the way we moved the ball and found space.
"We created so many chances through our excellent combination play and couldn't have been happier at half-time in terms of coming in ahead but we could have been three or four up.
"Of course, we're disappointed with the second half. They've switched their system and made their front three narrow which caused us problems.
"We were always trying to play our way out and all the space on the pitch was behind them which made it really difficult to get out."
