2011–12 Belgian Second Division  The 2011–12 season of the Belgian Second Division (also known as EXQI League for sponsorship reasons) started in August 2011 and is the second tier football league in Belgium. The league is played by 18 teams, with 34 matchdays of 9 matches each, so each team plays the 17 other teams twice. The season is divided into 3 periods, the first period of 10 matches, the second of 12 matches and the third of 12 matches. Each period winner qualifies for the Belgian Second Division Final Round. On 14 April 2012, Charleroi became champions without playing as closest rivals Eupen and Oostende both did not manage to win their matches and thereby could no longer mathematically overtake Charleroi in the standings. After promotion and relegation, only 13 teams remained in the league, with 5 other being replaced:      The season is divided into three periods. The first ten matchdays together form the first period, matchdays 11 to 22 form period two and the last 12 form period three. The three period winners take part in the Belgian Second Division Final Round together with the winner of the 2011–12 Belgian Pro League relegation playoff. The winner of this final round gets to play in the 2012–13 Belgian Pro League. In case one or more periods are won by the team winning the league or in case one team wins multiple periods, the extra places go the teams finishing the highest in the league not already qualified. So in the theoretical case that one team wins all three periods and becomes the league champion, then the teams in positions 2, 3 and 4 will take part in the final round. Already after the first nine matches of the season, Eupen clinched the first period title. "Including matches played on 29 April 2012; Source:Soccerway"
