Walter Smith declared Rangers want to keep in-form Kenny Miller after he grabbed a brace as the SPL champions came from behind to beat Celtic.
Miller's present contract is due to expire with the Glasgow club next summer and the two parties have yet to agree a new deal.
And, following his brace against Celtic, which takes his tally to 13 for the term, Smith would be loath to lose him.
He said: "We want to keep him and we will know at some stage whether we can or can't.
"Just now, we will enjoy the fact that we have managed to come here after a really tough week for us playing in the Champions League on Wednesday night. Coming here today would have been difficult for any team."
Both teams went into the game level on points after winning their opening eight league matches.
Gary Hooper gave Neil Lennon's men the lead just before the interval but a Glenn Loovens own goal and a Miller brace settled the game in Rangers' favour.
"We started both halves very well," Smith told Sky Sports.
"The first 10 minutes were the best that we have started at Celtic Park for a long while.
"We hit the post and then the game settled down and there was not much in it for either side and it was disappointing to lose a goal just before half-time.
"We started better in the second half and once we went in front McGregor made a couple of saves to keep us in front. I'm delighted to come away from here with a win.
"Kenny's been terrific for us and we didn't get close enough to him in the first half but we did in the second.
"Going into this match both teams had won eight of their matches and from that point of view the game was more important so I'm glad we won.
"It's a fantastic result for us, obviously going in one-nil down just before half-time was disappointing because we felt that we started the game really well."
Man-of-the-match Miller revealed that it was a half-time pep talk by Smith that gave them the inspiration for their second-half display.
Miller said: "Walter told us to be more confident on the ball and getting it moving quicker as we felt that we had started the better team.
"I think we sat off them a bit and you saw in the second half when we got at them we scored three second-half goals that gave us a bit of breathing space
"The result is the most important thing but to get on the scoresheet as a forward in these particular games is pleasing."
His team-mate Steven Naismith also paid homage to Miller's contribution to Rangers' season so far.
"We've had a few games that have been difficult and Kenny has popped up with the winners that's why he is a top striker," said Naismith.
"He's done brilliant this year. In the squad we have a good mix with David Weir, Lee McCulloch and Kenny at the spine of the team and you have young energetic boys around them and over the years we've showed that we are a good mix."
