Fabrizio Romano added on Twitter: "No formal bid made [by Liverpool] made yet - just contact to be informed on conditions of the deal."
Shortly afterwards, Liverpool had a bid accepted from Stuttgart for Japan international midfielder Wataru Endo, who is travelling to Anfield to undergo a medical.
Meanwhile, Amrabat has already stated his opinion on a move to English football amid interest from both Liverpool and United.Amrabat plays his club football for Italian Serie A side Fiorentina, and started last season's Europa Conference League final defeat to West Ham in Prague.He conducted an interview with The Times before the game, in which he left readers in no doubt as to his opinion of Premier League football.
He said: "Of course, the Premier League is a fantastic league, one of the strongest in the world.
"It would be nice to play there one day, but it's not that I want only to go to England, because Spain is nice. Serie A is a nice league.
"Football has changed a lot. It's more physical, you have more to be an athlete, the tempo and intensity is higher.
"Of course, in England, the intensity is very high. So I think it could suit me."
Whether he moves to Liverpool and United will surely become clearer in the coming days as the transfer window ticks towards its deadline.
