Tony Loughlan joined the Clarets as first-team coach under new manager Sean Dyche in October, 2012.
The pair had previously worked together at Watford and spent time together as young players at Nottingham Forest.
Loughlan, who joined Forest from non-league side Leicester United in 1989, also struck up a friendship with Roy Keane at the City Ground and later joined forces with the Irishman after starting his career in coaching.
Loughlan, who was born in January, 1970, moved from a position as Academy coach at Leicester City to join Kean at Sunderland as head coach in 2006.
The former midfielder then followed Keane to Ipswich Town when he operated as assistant manager from 2009 to 2011.
Following Keane’s departure from Portman Road, Loughlan then linked up with Dyche as part of the management team at Watford.
Dyche, Loughlan and Ian Woan enjoyed a successful 12 months at Vicarage Road before being reunited at Turf Moor.
