"Rangers cannot enable a Connor Goldson state of affairs once more. If he had a yr (left) you'll get good cash for Connor Goldson, little doubt about it.
"I believe Rangers will likely be sitting down with these guys and seeing what sort of vibe they get. In the event that they need to strive one thing completely different, and in the event that they do then Rangers may have to go and promote them.
"When it comes to Bassey, I'd be very shocked if Rangers have not sat him down for the reason that Scottish Cup ultimate. I'd have sat him down as quickly as he got here into the dressing room.
"He's Rangers largest asset now.
"The three gamers I discussed, you're speaking £30million plus for the three of them.
"I actually suppose they cannot let the Goldson factor occur once more.
"(Bassey) He has was a high participant. When you drew a centre again you'll draw Calvin Bassey.
"For me Rangers have gotten to get him tied down and simply say to him have a full season right here, proceed your improvement after which you're speaking about Kieran Tierney degree (worth)."
