A vastly experienced player, Danny, whose favoured position is central midfield, has joined from Connah's Quay Nomads, for whom he played for 6 seasons, winning two Cymru Premier titles, the Welsh Cup and the NMG Cup during that time.
Born in Liverpool, Danny was a product of the Tranmere Rovers youth system. Joining the club as a 13-year-old, he was granted his first team debut in the 2001–02 season at home against Wigan Athletic. Harrison was a regular in the centre of midfield in the Brian Little era, but under Ronnie Moore he found opportunities harder to come by and signed for Rotherham on 25 May 2007. After 5 years with the Yorkshire club he was released in May 2012, and rejoined Tranmere on a one year deal.
The following summer he dropped into the Conference National when he joined neighbours Chester, making 29 appearances, and scoring 2 goals. In 2015 he made the transition into Cymru Premier football, when he joined the Nomads.
