Both players departed the Dons earlier this summer, but as we’ve told you in the past, Jack’s move caused a lot more controversy, and he was heavily criticised by the club’s supporters.
Hayes will probably be given a warm welcome upon his first return to Pittodrie next season, whilst Jack’s will be a little more frosty – to say the least.
And speaking to the Sunday Post, Hayes gave his thoughts on the eventful transfer window, saying: “Is there a contrast between the moves? It is hard to say. I can only really worry about myself on that score.
“Ryan could have been comfortable in Aberdeen, but he fancied a new challenge so he has moved himself and his family down to Glasgow and good luck to him. You have got to challenge yourself in football.
“I do think he will settle in well at Rangers, because he is a fantastic player who could settle in anywhere.
“In terms of my own move, it has been received OK because I think I went about things the right way. I have got a good friend who lives in Glasgow and is a lifelong Aberdeen fan and that is how he feels.
“The manager always said if a big club down in England or a Celtic came in, I could go.
“Celtic was always the dream move for me, but I think I have a good relationship with Aberdeen. Since I left, I have been in touch with the chief executive, the manager, the assistant manager and the players.
“I have been keeping a close eye on them since the move and I’m delighted they have Ryan Christie on loan and Greg Stewart coming in, plus they have managed to keep Kenny McLean.
“You quite often don’t hear anything about their business until the last minute, but they will be working away on strengthening behind the scenes and I will be quite happy if they are second again this season.”
Jack and Hayes will meet whilst playing for their new sides on September 23, when the Hoops travel to Ibrox for the first Old Firm match of the season, whilst the Gers don’t face Aberdeen until October 21.
But what do you think of Hayes’ theory? Has he handled his situation better than Jack?
