Gers have made two offers for the Brighton defender since the end of last season.
“You've got an idea but it's only when you go up there that you realise how big it is. Just walking around the streets, it's a giant of a football club with a great fanbase.
“For me it was a bit wrong place, wrong time. The club was a bit all over the place and then a change of manager, who was an interim manager anyway (Graeme Murty).
“But I loved playing for a football club of that size and that support. I think the level is different. The top four, Aberdeen, Hibs, Rangers and Celtic, with Kilmarnock and Hearts just floating outside of them, are a really good level, easily Championship level those four.
“After that it's a different standard to the Premier League and Championship. Every team, especially playing for Rangers or Celtic, it's a cup final every game, teams are desperate to beat you so you have to cope with that pressure and expectancy.
“It will certainly be different for him. I guess for Connor at this stage of his career it will be for him to decide whether he wants to go up the road and compete to win things or whether he has got a burning desire to stay here and try to get back in the Premier League and play in the Championship regularly.
“That will be his decision but it is some football club. If anyone asked me would you sign there I'd always recommend doing it. It's got everything there, it's just waiting for lift-off.
“They've had a tough four or five years but they are slowly steadying the ship and turning it around."
