JOEY BARTON admits his decision to leave Burnley was the 'toughest of his professional life' as he closes in on a switch to Rangers.

The midfielder is poised to pen a two-year deal at Ibrox and become the highest profile signing of the Mark Warburton era.

Barton was named in the Championship Team of the Year as he helped the Clarets clinch their return to England's top flight this term. But it is the Scottish Premiership where he is now set to play his football next season as he looks to inspire Warburton's side to title glory.

The 33-year-old confirmed his departure from Turf Moor on Twitter this morning and said: "Thanks to all the Burnley fans and everyone connected to the club. Amazing support this year that will live with me for a lifetime.

"Toughest decision of my professional life to leave an amazing set of people and a phenomenal culture behind. "Club is in a great place on and off the pitch with great custodians at the helm.

Thanks again for the opportunity to represent your club. "I was presented with an opportunity and challenge the competitive animal in me just could not turn down. Onwards and upwards now x"
