Hull manager Steve Bruce has already confirmed talks have taken place about signing Sagbo, with the newly-promoted Premier League club reported to have bid £1.6million for the 25-year-old former Monaco forward.
Although Evian did not name Hull in a short statement, or confirm a fee had been agreed, they said Sagbo had been given the go-ahead to hold talks with a club in England.
Evian announced on their website: "Evian Thonon Gaillard FC have authorised Yannick Sagbo to go to England to visit the facilities and meet the leaders of a club, in the case of an eventual transfer."
Regarding French-born Ivorian Sagbo, Bruce yesterday told the Hull Daily Mail: "We're in conversations.
"My chief executive is speaking with Evian and we're hopeful that we can get something done because he would be a good addition.
"He's a little bit different to what we've got. He's quick, he's direct and he wants to run in behind.
"It's hard talking about a player who belongs to another club but there has been dialogue and we'll see where it takes us. We'll be patient and see what develops."
