Rangers boss Walter Smith set his sights on their midweek UEFA Cup showdown with Osasuna after defeating Celtic 1-0 in Sunday's Old Firm derby.
The Gers travel to Spain for the return leg of their last 16 clash with the in-form La Liga side with the scores level at 1-1 but buoyed by Ugo Ehiogu's 50th minute winner at Parkhead.
"Celtic started really well and looked very bright. We rode our luck for the first 25 minutes and gave away too many free-kicks," he said.
"We passed better and quicker in the second half and got our goal from set-play, which looked the only way either side was going to score.
"I am delighted to win and we've a big match next Saturday against our closest challengers for second place, Aberdeen.
"We can look forward to the game in Spain now and Kris Boyd was rested as we play five games in 13 days.
"I thought Filip Sebo played really well and put himself about."
