Dean Keates admitted Wrexham’s performance in the 2-0 National League defeat at Fylde was their worst of the season.
The Dragons saw their 11-match unbeaten league run ended at the ground where they crashed out of the FA Cup 10 days ago.
Keates admitted of Tuesday’s setback: “It wasn’t an off night. It was by far the worst performance of the season and I can only apologise to the fans – an unbelievable following.
“You can look at reasons why. We’ve had a good chat in there. A few people have got a few things off their chest.
“We’d gone 11 games unbeaten in the league, a good result at the weekend and we came here with standards, and that was nowhere near.”
Wrexham had gone into the game buoyed by Saturday’s victory at promotion rivals Dagenham & Redbridge.
But Jonny Smith gave the home side an early lead after Dragons keeper Chris Dunn could only parry Danny Rowe’s free-kick.
And Jack Muldoon late solo effort ensured Wrexham another sorry trip to the Lancs coast as they suffered a fourth defeat of the campaign.
But Keates’ side remained in third place three points behind new leaders Dover after Macclesfield lost at Dagenham & Redbridge.
