Borna Barisic insists Rangers pal Calvin Bassey has the mental fortitude to improve even further at Ibrox.
And the brains pairs well with his considerable brawn as Bassey has emerged as a stick-on starter in Light Blue.
Gio van Bronckhorst is a huge fan of the Nigerian international, who has fitted between left-back and centre-back so far this season having been signed from Leicester City by Steven Gerrard last summer.
And he's popular in the dressing room too, even among his competitor for the position.
Barisic said: "He’s my boy! He’s a good guy and a very good player.
"I think he has improved this season very well and he can play both at left-back or centre-back.
"But we know his qualities. He’s very strong and it is very tough to play against him.
"I’m pleased that he has improved this much and I think he has a very bright future.
"He has the ability but even more important is that he is very calm and down to earth.
"He is strong mentally and he always wants to learn from everybody and wants to listen.
"I think that is a thing which is even more important than all the ability he has. This is the main reason I think he has a very bright future in football."
