Celtic take on SuperSport United in the League on Tuesday night and Larsen has urged his team to try and remain focused despite their Cup elation after beating mamelodi Sundowns on Saturday.
"We can't rest on our laurels now and start slumping in the League. Celebrations will be put on hold until our last game before the mid-season break," Larsen says.
"It is business as usual, it's a difficult period now, where the guys have to remain focused for the remaining games which is not an easy task," he adds.
Larsen wants his team to try and replicate the form they showed in Cup action in the League.
"A lot of our players have experienced this hype and euphoria for the first time in their careers so now it’s up to myself and the technical team to keep them focussed, especially the youngsters, so that we finish the remaining four League games just as well as we did in the Cup," he adds.
