It was here that the winger became regular for the team, helping the club to a runners-up position at the 2010 and 2012 editions of the CAF Champions League and actually winning the competition in 2011.

Following this triumph, Bouazzi would also go on to feature at the 2011 FIFA Club World Cup as his team was only able to manage a sixth place finish.

During his time with Espérance, in domestic play the club won four league titles and three Tunisian Cups.

In the summer of 2013 Bouazzi joined FC Lausanne-Sport, his first club abroad, and competed in the Swiss Super League after signing a two-year contract.

He made his debut in a 2014 FIFA World Cup qualifier against Cape Verde on 9 June 2012 with the team claiming a 2-1 away win.
