Rangers boss Walter Smith was dejected after losing out to Hapoel Tel Aviv in the first leg of their Uefa Cup tie.
McCoist and Smith thought Rangers should have had a penalty
"I don't think we deserved any better than a draw," he told BBC Sport after the 2-1 defeat in Israel.
"Neither side created much and there was not much between the teams but I was disappointed at the goals we lost.
"I thought the free kick for their first was soft and we didn't set up well for it, while we could have defended better for their second goal."
Both Smith and his assistant Ally McCoist were upset not to get a penalty when a defender handled a header from David Weir early in the second half.
"It looked very like it, didn't it?," said Smith when quizzed on the incident.
"Overall, there was a lot of free-kicks given rather easily by the referee in important areas of the pitch but when it came to an important one for ourselves he didn't give it."
McCoist was more vociferous and told BBC Sport: "I couldn't believe we didn't get a penalty for that!
"But we got an away goal so we're not too downhearted.
"It was important to get a goal and we are certainly still in this tie."
