Josh van der Flier says Leinster want to take away Connacht's belief by not allowing them into tomorrow's Champions Cup second leg at the Aviva Stadium.
The Ireland flanker and his Blues colleagues know that the westerners will grow in confidence if they are allowed into the tie with a similar start to last Friday's first leg in Galway.
The aim, therefore, is to kill off any chance of giving Connacht a foothold in the tie as the underdogs look to quickly erase their five-point first leg deficit.
