Summer signing McGregor has starred since returning to Rangers in the summer.
Rangers goalkeeper Allan McGregor has told Sky Sports that he feels as good as he did a decade ago, when asked about retirement and how long he can continue at the top level.
Now 36 years of age, McGregor is in line to win his 40th cap for Scotland as Alex McLeish's side face Israel on Thursday night in the UEFA Nations League before challenging Portugal on Sunday afternoon.
McGregor has arguably been Steven Gerrard's best summer signing at Rangers, since the Liverpool and England legend took over at Ibrox. Gerrard brought in 15 new players in the summer, with McGregor signing a one-year deal.
Asked about his future plans and potential retirement, McGregor stated that he felt better than he did 10 years ago because he is looking after his body after watching former Rangers star Davie Weir do the same.
"I don't know how you're supposed to feel when you're 36," McGregor said. "But I don't feel any different to how I felt 10 years ago - probably feel better actually.
"I used to watch Davie Weir do it, you're in the gym every morning; stretching and doing your bits and bobs. When you get older, it's not a chore, you just realise that it needs to be done to keep going.
"I suppose it depends on your mental state and injuries as well, if you still want it and at this moment in time I obviously do."
Making 17 appearances in all competitions for Rangers, McGregor has kept seven clean sheets in 17 league and cup outings - conceding only 13 goals in that time.
It remains to be seen if McLeish has picked a number one for this international break's matches with Craig Gordon vying for the slot between the sticks.
Last month, McGregor was given the task of keeping goal in the competitive Nations League fixture, while Gordon faced Belgium in a friendly.
