Thierry Henry believes the hard work is still to come for France as they look to book their place at the 2010 FIFA World Cup South Africa™ at the expense of Republic of Ireland.

Raymond Domenech's men will take a 1-0 advantage into the second leg of their play-off in Saint-Denis tomorrow, courtesy of Nicolas Anelka's deflected goal in Dublin on Saturday.

Even a draw at home to the Irish would now be good enough to send Les Bleus to the world finals, but Henry has insisted there is absolutely no room for complacency.

The Barcelona forward is eager to make sure the hard work his side have put in during a qualifying period - in which they have had things far from their own way - does not go to waste.

"The hardest thing will be to finish the job," the former Arsenal player said at France's Clairefontaine training base. "The plain truth is that when we get on the field it will be 0-0.

"We will approach this match as if it was a one-off. We said right away there were 90 minutes still to play. We've been fighting to qualify for the last two years. The Irish will not give up."

Indeed, the visitors will take hope from the fact that during qualifying, France could only draw with Romania and left it late to beat Lithuania at home.

France will be without defender Eric Abidal with a thigh injury, with either Julien Escude or Sebastien Squillaci in line to replace him.
