Mullin has excelled in the National League and League Two over the past four years, averaging 30 goals per season across the divisions for Wrexham and former club Cambridge. But League One is an altogether different challenge for him, having spent only half a season in the third tier in his entire career - scoring just three times in 20 appearances for Tranmere Rovers in 2019/20. But with greater maturity, experience and momentum, he will relish the opportunity to prove himself all over again in 2024-25.
