The Serbia international says he's excited about the deal.
"We have reached an agreement for three years, with the option to extend with another season. I have yet to undergo a medical exam, but that shouldn't be a problem," said Jovanovic to Sporza.
"I don't have any physical problems and I'm feeling perfectly fit. I opted to sign for Liverpool because they're one of the biggest teams around in Europe. They're definitely among the 10 biggest sides.
"I'm absolutely delighted that the deal is completed. From now on, I can focus on Standard Liege again. I want to leave the club in a good way."
