Mbappe has emerged as a Reds transfer target in recent weeks despite Paris Saint-Germain's insistence the World Cup-winning forward is not for sale.
Liverpool supporters noticed that the forward even recently started following current and former Reds players on Instagram.
He even said he'd pick Liverpool as his team to play with on FIFA if he was facing off against someone for money, simply because they are the Champions League winners.
Mbappe was asked about his future in a recent interview with ESPN and admitted he could one day finish his career in America, like Steven Gerrard before him.
"We don't know what happens in football," said the Frenchman.
"Now in the USA, a lot of great players come after their careers in Europe, like Zlatan Ibrahimovic, Steven Gerrard, Frank Lampard, Andrea Pirlo, great players. You don't know what can happen, maybe when I'm a little older I can think about this."
