The football legend's tweet came as results were still coming in last night and a few hours later Nigel Farage was giving a victory speech for Brexit.
The Ukip leader said: "He said: “The dawn is breaking on an independent United Kingdom!
“We have fought against the multinationals, we have fought against the big merchant banks we fought against big politics, we fought against lies, corruption and deceit.
“And today honesty, decency and belief in nation I think now is going to win.
“And we will have done it without having to fight, without a single bullet being fired.
“We will have done it by damn hard work on the ground, by people like my friend Mr [bankroller Arron] Banks here. And by people in the Labour party and the Conservative Party and of Ukip and no party.
“I hope this victory brings down this failed project and leads us to a Europe of sovereign states.”
The speech drew heavy criticism for his line "without a single bullet being fired" in light of the murder of MP Jo Cox last week.
Jo Cox was shot and killed last Thursday in Birstall, near Leeds.
The attack came on the steps of the town library just before 1pm, where the 41-year-old mother-of-two had been holding a surgery with her constituents.
Cox, who was elected to the Commons last year as MP for Batley and Spen, was rushed to Leeds Infirmary hospital by air ambulance after apparently being shot twice and stabbed.
