Rangers boss Steven Gerrard has suggested that his first-team squad may have "spoilt" him during the opening weeks of his reign.
The England legend has acknowledged that his side had put themselves in a strong position, but the 38-year-old has revealed that he had been left unhappy with the first-half performance at Ibrox.
Gerrard told RangersTV: "I was disappointed in our first-half showing. I just felt that we were a gear down today, a little bit flat, but maybe I'm expecting too much, too soon because the players have spoilt me.
"I've got belief and confidence in my players that we can go and finish the job off. We need a performance full of heroes and warriors next week."
Rangers will face Motherwell on Sunday before making the trip to Russia for the second leg, which takes place next Thursday.
