Wrexham manager Phil Parkinson has attacked Charlton boss Nathan Jones for showing a lack of respect for the Welsh side.
Jones, who previously managed Southampton and Luton, described the Reds as a 'circus' ahead of their crucial top of the table clash in League One on Saturday.
Wrexham, owned by A-listers Ryan Reynolds and Rob McElhenney, are looking to clinch a third consecutive promotion and a return to the second tier for the first time since 1982.
Parkinson's men sit in second, four points above fourth placed Charlton, and two points above Wycombe Wanderers in third, with just two games left of the campaign.
