Many thought Warburton had pulled off a genuine coup when he signed Barton to a two-year deal in the summer of 2016, but the Englishman’s stay in Scottish football lasted just eight matches – with his last appearance in a light blue shirt coming in the crushing 5-1 defeat to Celtic.
Barton was suspended by the club after a bitter fall-out with Warburton and team-mate Andy Halliday in the wake of that defeat but it appears both parties are happy to let sleeping dogs lie.
Speaking in an interview with the Sun, the former Nottingham Forest and Brentford coach explained: “We were widely praised at the time for signing the likes of Joey Barton and Niko Kranjcar.
“Over 40,000 season tickets were sold. We’d made a statement of intent bringing in someone who was Championship Player of the Year at Burnley.
“Hindsight’s a marvellous thing. But life’s too short for lingering bitterness. We’ve since wished each other well.”
So, what do you make of Warburton’s comments? Should Barton signing for Rangers still be considered a mistake, or do these things sometimes just happen in elite sport?
