Huddersfield Town Under 21 coach Frankie Bunn says concentration is crucial as his side gear up for the Professional Development League II play-offs.

Town are assured of the North section title with three regular-season games to go, starting with a Monday afternoon clash with possible semi-final opponents Cardiff City at the John Smith’s Stadium (1.00).

Bunn’s side then have two away games, against Birmingham City on Thursday and Coventry City next Monday, April 25, before a home play-off semi-final against the South section runners-up (Cardiff are currently second to Charlton Athletic with Millwall and Colchester United still in the hunt).

Town have made the play-offs ever season since the inception of the PDL in 2012-13. But they have never won them, losing in the semi-finals in 2013 and 2014 before going down 3-2 at Swansea City in last season’s final after beating Crystal Palace 5-3 after extra time.

Town, who made the last four of this season’s Under 21 Premier League Cup, losing on penalties to Hull City, have won their last three to make it 19 victories in 27 league games.

Bristol City were beaten 4-1 last time out with goals by Rekeil Pyke (2), Fraser Horsfall and Lewis O’Brien.

“We’ve played better this year, but our set plays were very good, and we scored from three of them,” said Bunn. “We were clinical. We soaked up a bit of pressure and looked very threatening on the counter-attack.

“Set-pieces in both boxes are so important in any game of football, at any level.

“Unfortunately we conceded one in the final minute and although were 4-0 up at the time, we can’t be complacent or sloppy.

“Somebody let a runner come off them from a corner and has been spoken to, so I hope it won’t happen again.”

The Under 18s missed out on a PDL II play-off spot after a 3-3 home draw against Coventry City.

Jack Boyle (2) and Dom Tear were on target, but Sheffield United’s 7-1 home win over Hull City ensured they finished second to Nottingham Forest in the Northern division.
