“And Hibs will also be bolstered by what turned out to be a very good piece of business by the Edinburgh club,” the 37-year-old wrote in The Daily Record.
“They were never going to sell Allan to their promotion rivals. It was well within their rights to resist Rangers’ bids and I’d suggest the fans should move on from that and not let any bad blood fester between the clubs on Sunday.
“However, although Allan was never going to Rangers it looked clear that his head had been turned and with his heart set on moving to a bigger challenge, it was wise of Hibs to let him go.”
Selling Allan to Rangers would have strengthened the Gers, and Hibernian understandably did not want to do that.
Both Rangers and Hibs are fighting for the Scottish Championship title this season and aiming to get automatic promotion to the Scottish Premiership.
Mark Warburton’s Rangers side have won both of their league games so far, while Hibernian have picked up three points from their opening two league matches.
