McCoist has admitted he would like to strengthen his Gers squad during the January transfer window - with another hitman his top priority.
But Mohsni thinks his side can maintain their winning run in SPFL League One and challenge in the Scottish Cup with the forwards they currently have.
Clark scored four goals in the emphatic 6-1 win over league rivals Forfar Athletic at Ibrox on Tuesday night to help them break their post-war record for consecutive wins. And Daly has been immense for the Glasgow giants and has banged in 13 goals in all competitions.
Mohsni squares up to the deadly duo every day in training at Murray Park and reckons a new striker would struggle to get a game ahead of them.
The centre half said: "Nicky did very well against Forfar. He was on fire. He deserved all of his goals. He tries to hold the ball up as well as score goals.
"He will just get better and better. He is a young player and he needs more confidence. He is very quick and is a good finisher.
"In the game on Tuesday night and the games before that Jon Daly and Nicky Clark showed that we don't need another striker. They are scoring goals for fun."
Mohsni likes to get upfield and attack and has scored six times for Rangers since arriving at the Govan club on a free transfer in the summer.
But he is happy to concentrate on defending with Clark and Daly in such scintillating form.
He said: "I think my place is at the back for the rest of the season."
Mohsni believes the Scottish Cup defeat that Motherwell suffered at the hands of minnows Albion Rovers at the weekend shows how challenging life in League One can be for Rangers.
But the French-Tunisian player is still determined for Rangers to maintain their winning run and record a "Perfect Season".
He said: "You saw in the Scottish Cup how hard beating the lower league teams can be.
"We play these teams every week. It is not easy. Every game is very hard. Every team starts very well every time we play them. We have to be very strong.
"Every Saturday and Tuesday night is like a Scottish Cup game for us. You have to work hard and concentrate.
"I think we can win every game. We have proved that we are a strong team in defence, in midfield and up front.
"I think Arsenal did it, went the whole season without losing a game. They were called the Invincibles. If we did it we could be called the Invincible Champions."
Mohsni, though, wonders whether McCoist may try to give some of the young players at Rangers some game time if they sew up the League One title early.
He said: "It would be the highlight of my career.
"I think everyone wants to win the league quickly. I think to keep winning games will be the motivation when we win the league.
"But maybe after we win the league the manager will put the youth players in to give them experience."
Meanwhile, Mohsni has dismissed claims by Falkirk player Conor McGrandles that Rangers are not good enough to win the Scottish Cup this season.
He said: "I think he was upset at the defeat and when that is the case you say some rubbish stuff. We will see. We have to prove to everyone that Rangers can win the Scottish Cup."
