Bristol Rovers host in-form Barnsley at the Mem on Saturday and Joey Barton believes it is the most difficult game the Gas have left to play this season.
Michael Duff, a good friend and former teammate of the Rovers boss at Burnley, has the Tykes in fine form, winning four straight to move into automatic promotion contention, and Barton has huge respect for the job his old pal from Turf Moor has done at Oakwell.
Rovers have the likes of league leaders Sheffield Wednesday and second-placed Plymouth Argyle to face in their final 13 games of the League One season, but stylistically he admits sixth-placed Barnsley pose them the biggest threat.
