http://en.wikipedia.org/wiki/2013_Africa_Cup_of_Nations_qualification#First_round says there will be a qualifying for for the 2012 Africa Cup of Nations with the first legs on February 29 and the second legs on June 15, 16, or 17. There are no FIFA matchdays in between February and June. Does anybody know of a longer gap between two legs of an aggregate goals series?
Coventry and St Mirren are still awaiting the 2nd leg of their Anglo-Scottish cup tie. The first was played in 1987.
