Joe Gallen is an experienced Assistant Manager, who was appointed at the club on June 11th to join Kenny Jackett.
Gallen, who has a long-standing relationship with Jackett, reunited with him to work together for a fifth time – with the pair most recently together at Portsmouth.
He first joined up with Jackett at Milwall in 2013, having worked together previously at QPR, and has since been his trusted no.2.
“I’m very pleased to be here, and it’s a fantastic opportunity for me to come in with Kenny. On the back of a solid season for the club last year, we’re looking to improve upon that,” said Gallen.
