Speaking to Sky Sportsafter the game, Mullin said: "It's not just about me. It's a real team effort. When I first joined, Rob McElhenney told me: 'Championship in five years'. We've done it a year early. It's been some journey, unbelievable. These fans f*cking deserve it. Sorry for the language. [It's an] unbelievable feeling. I'm so happy for everyone involved. Phenomenal.
"I've found it hard not being involved as much this season, but I will enjoy this one just as much. The question I got asked when I signed here was: 'Why Wrexham? Why Wrexham?' Here's your answer for the third time in a row. It has been phenomenal; we've created history yet again. Back-to-back-to-back, never been done, it has now and it belongs to Wrexham. I'm so happy for all the fans."
