Tunisia coach Roger Lemerre thinks the foundations now need to be laid to build a younger squad that can succeed in South Africa in four years time.

The north African side finished third in Group H after taking only one point from their three matches and are heading home after a disappointing tournament.

After Friday's 1-0 defeat to Ukraine that confirmed Tunisia's exit, Frenchman Lemerre said: "I don't know whether we have progressed or regressed, that's the big question mark.

"I think we must work tremendously on the building and pre-building of players in order that we can have young players reaching international tournaments.

"We certainly share the disillusionment of the Tunisian fans but life goes on and we now have to think about qualification for the next African Nations Cup as well as the next World Cup."
