The senator of Montserrado County - once named Fifa World Player and victor of the much coveted Ballon d'or - defeated his 73-year-old opponent Vice President Joseph Boakai in a landslide victory in results announced in Liberia on Wednesday morning.
Boakai waged a bitter legal battle over problems with queue control and voter identification in the October 10 first round.
"You know I've been in competitions - tough ones too and I came out victorious".
They are selecting a victor between George Weah and Joseph Boakai to succeed Africa's first elected woman President Ellen Johnson Sirleaf.
Ms Sirleaf took office in 2006, after her predecessor President Taylor was forced out by rebels in 2003, ending a long civil war.
"The electoral commission has two weeks to declare the results, but officials they will do so within four days".
Orrin Hatch Trolls Utah Newspaper That Wants Him To Retire
But Matt Whitlock, Hatch's communications director, made clear in a Tuesday tweet that Hatch's seemingly approving tweet was "tongue-in-cheek".
"I believe that whenever we give him a chance, he will be able to give a better Liberia to the youth and the homeless", Andrew Janjay Johnson, a shoeshiner in a Monrovia market, told AFP. "I have the people on my side".
"George Weah is in a stronger position than in 2005", said Ben Payton, head of Africa research at England-based risk consultancy Verisk Maplecroft.
He and Boakai voted in polling stations near their homes in Paynesville, a suburb of Monrovia, the capital of this nation of 4.6 million people.
Meanwhile, 73-year-old Liberian Vice President Boakai is viewed as a "continuity candidate" and has won praise for his involvement in public service which spans four decades.
The former Liberia national captain will now succeed his great rival and incumbent, Ellen Johnson Sirleaf as the 25th president of Liberia.
