On 21 November 2013 Buaillon agreed a move to Football Club Sion, being effective in January of the following year. He appeared in only three matches for the Swiss side (169 minutes of action), which finished eighth. On 30 June 2014 Buaillon signed a three-year deal with Standard Liège, being subsequently loaned to AD Alcorcón.
However, after being deemed suplus to requirements by manager José Bordalás, he moved to Paris Football Club also in a temporary deal.
