The pundit recently suggested the Gunners need three more players to compete for the title.
The Gunners are currently top of the table and two points clear of second placed Leicester City, with many believing they could win the title come the end of the season.
Shearer however believes they are short of the players necessary to finish as winners, telling the BBC that they need three new players to be proper contenders.
Giroud doesn’t agree though, and has rubbished that suggestion, instead insisting that they have a squad is more than capable of finishing the task.
“Tell me where! Just tell me where! I will explain the opposite judgement,” the Mirror reports him saying.
“We have very good players as well on the bench, young players waiting to come in. They are very talented. I am not worried about it.”
“Danny Welbeck will come back in a month and a half. Theo Walcott can play up front; Joel is Campbell doing well with his national team up front. If I am less good or get injured, we still have a solution.”
While Giroud clearly feels that the squad is good enough as it is, Arsenal fans are sure to be keen to see new faces arrive in January and provide a boost in the second half of the campaign.
In fact, that is something that manager Arsene Wenger has apparently already moved to do, with the arrival of Mohamed Elneny imminent according to Sky Sports.
That early arrival suggests the French boss is more in mind with Alan Shearer than his current centre forward on whether Arsenal need to strengthen.
