Having spent the best part of a decade at Pittodrie, and several seasons as club captain, Jack had become a fan favourite at Aberdeen – but he seems to have completely tarnished his reputation there now.
After running down his contract, Jack joined the Ibrox club today on a three-year deal, and follows Bruno Alves as Pedro Caixinha’s second summer signing.
Some Aberdeen fans are insisting they’re not at all bothered about Jack leaving but others are finding it a lot more difficult to hide their outrage:

You get the gist.
It’s probably for the best if Jack gives Twitter a miss for the next few days.
What do you make of his move? Is he exactly the kind of player Rangers need?
