Burnley secured the signing of former Brighton and Hove Albion striker Barnes on a three-and-a-half year deal in January 2014.
The Somerset-born hitman became the first player that manager Sean Dyche paid a fee for, 18 months into his reign, having scored 42 league goals in over 150 appearances for the Seagulls.
And it was the culmination of a season-long pursuit of the striker, who bolstered the Clarets strike force and scored three goals, in support of regular strike duo Danny Ings and Sam Vokes.
That helped contribute to the Clarets achieving promotion to the Premier League just five months after his arrival, with Barnes scoring the goal of the season in the decisive win over Wigan at Turf Moor.
Barnes then forced his way into the starting line up in the top-flight, eventually finishing joint-second top scorer with five goals to further enhance his reputation.
However, his Premier League campaign ended in huge disappointment when he suffered a serious knee injury on the final day at Aston Villa; a setback that ruled him out for most of the 2015/16 Championship campaign.
He did, however, return to the Clarets side against former employers Brighton & Hove Albion in April, before starting in the 2-1 victory over Birmingham City at St Andrew's.
Ashley began his career at his local club Paulton Rovers, where he established himself as a prolific goalscorer and, after impressing in a trial with Plymouth Argyle, was rewarded with an 18-month contract at Home Park in 2007.
However, Barnes found first team opportunities hard to come by at Argyle and soon spent time on loan with Oxford United and Salisbury City.
He enjoyed further loan spells with Eastbourne Borough in 2008 and Torquay United two years later, before subsequently joining League One Brighton and Hove Albion, initially on a season-long loan, where he scored on his debut against Tranmere Rovers.
In July 2010, Barnes signed a two-year contract with Brighton after joining for an undisclosed fee and, in April 2011, scored the decisive goal in a 4-3 home victory over Dagenham and Redbridge, which confirmed promotion to the Championship.
After ending the season as Brighton’s second top scorer, with 20 goals in 49 appearances, the 2011/12 season saw Barnes remain as first choice striker for the Seagulls.
And he went one better, topping the club’s scoring charts with 14 in all competitions.
Barnes is also an Austrian international, having made an appearance for the Under-20s in 2008, when he faced Switzerland.
