James McDonaugh believes Hibernian's under-20 team need to learn how to roll their sleeves up and tackle the task in hand after watching the side lose the Mini Derby 1-0 at Newtongrange.
Hearts took an early lead - inside the opening five minutes - and dominated the first half before Hibernian staged a comeback, but the young team in bottle green were unable to conjure up an equaliser.
As a result, Head of Academy Coaching McDonaugh says a valuable lesson was learned on the night - the players need to adapt quickly to the circumstances and show a winning mentality at all times.
McDonaugh said: "I thought we took too long to get to grips with the game and basically one costly mistake ends up being the difference in the end.
"Despite improving after half time, we didn't create enough chances whether through good team play or an attacker engineering something for himself.
"The players are brought up to play football but in games like this and on a pitch that wasn't conducive to passing the ball we lacked the know-how about how to adapt.
"We must learn how to play different styles of football and learn that nice football and nice players don't always make the grade."
