But the centre-half is confident the Ibrox club will not struggle again in the William Hill Scottish Cup quarter-final replay this evening.
For he reckons there is no chance Ally McCoist's side will pass up so many chances in front of goal at New Douglas Park.
The Cliftonhill club frustrated their out-of-sorts opponents with an ultra-defensive approach in the last-eight tie. And the chances are high that James Ward's part-time side will adopt exactly the same tactics tonight despite being at "home".
But Mohsni, a regular scorer this season, believes the Rangers players, who were heavily criticised after the first result, have a point to prove.
He said: "It is difficult to play against a team that defends so deep against us.
"But this is a different game at a different stadium.
"We had a lot of chances against them in the first game and only took one of them. They defended very well on the day and deserved to get a draw.
"But we are confident that we will not pass up so many chances in this game. We are confident going into this game that we can score goals and win the tie.
"Over the course of a season we are not going to play well all of the time. Sometimes we will have disappointing games. That is what happened to us in the first match against Albion Rovers.
"We all believe we can go further in the Scottish Cup, through to the semi-final and enjoy a successful competition this season."
McCoist rested key players such as Jon Daly, Nicky Law and Lee Wallace in the SPFL League One game against Dunfermline at Ibrox at the weekend.
And he also took off Mohsni and captain Lee McCulloch in the second half of the 2-0 win to give them a much-needed break before the rematch with Rovers.
The defender believes the team, who will be rewarded for a victory with a semi-final match against Dundee United at Ibrox, will be fresh for their cup replay.
And he also thinks finally landing the third-tier title last week, with eight games of the season remaining, will have boosted the team's confidence.
He said: "It has been a long, hard season for us and a lot of the players in the team have been involved in a lot of our games home and away.
"So it was good that the manager was able to rest some players at the weekend and give others a run in the side. I think it will help them.
"They will feel refreshed for the cup game and hopefully that should help us to get the result that we want and to progress to the next round of the competition.
"It was also good to see some of the young boys who have been doing well get a chance and I am sure they will continue to feature between now and the end of the season."
Mohsni added: "It was a great experience winning the league against Airdrie last week.
"It is the first league I have won in my career and I enjoyed the night.
"Yes, people have criticised us for our performances and for the result against Albion Rovers. But we have not lost a game in the league so that has to be a positive achievement.
"We believe we are a good team. One result does not make us a bad team.
"I think if people look at our results over this season they will be able to see that."
Andy Little and David Templeton are both unavailable for the rematch with Rovers after sustaining injuries in the game against Airdrie.
But Nicky Clark and Kyle Hutton are available and came on against Dunfermline at the weekend.
And Mohsni is confident that Rangers have enough firepower up front to cope with this outing and with the remaining matches of the 2013/14 campaign.
He said: "Rangers is not just about one or two players, it is about the whole squad.
"When a player drops out of the team there is always another player waiting to take his place.
"It has been good to see both Nicky and Kyle in training. We know what good players they are.
"We have scored goals in every game that we have played in this season and are confident that whenever we go out on the pitch, no matter who is playing for us, we can score.
"We are not taking Albion Rovers lightly in this match, but we are confident we can do better than we did in our first meeting with them at Ibrox and go through."
