Looking to gain more playing time, De Pierro went on loan to second division club Football Club Stade Nyonnais for the duration of the 2011-2012 season. Returning to Young Boys, the player went on loan again to a second tier side, this time joining Football Club Lugano for the 2012-2013 season. In the summer of 2013 De Pierro signed for Football Club Lausanne-Sport on a two year contract with an option for a one year extension.
In a bid to reduce their squad, he was allowed to leave Young Boys for Lausanne despite the fact that his contract was set to expire in 2014.
