Isak's transfer to Liverpool was a long time coming, and he had gone on strike for the entire summer to push for the move away from St James' Park. Despite the controversy surrounding his departure, Gordon took the time to say goodbye to Isak on social media.

Gordon posted a heartfelt message on Instagram, saying: "It's been a pleasure to play with you, regardless of the situation.

One of the best on-pitch partnerships I've had, and more importantly, a great person and team mate. I wish you all the best, brother."
