After two further seasons on the bench with the Basel first team squad and a number of appearances in the reserve team, Leutwiler was loaned out to Yverdon-Sport for the 2009–10 season. The following season, he was loaned to FC Wohlen, but he was unable to hold the first-choice goalkeeper position, so returned to Basel. During the second half of the 2010–11 and the first half of the 2011–12 season, he played for the Basel U-21 team again. On 27 January 2012, it was announced that he would be loaned out to FC Schaffhausen until the end of the season.
