All three sides have been handed a major boost in their pursuit of the Argentina international, with his two-and-a-half-year spell in Amsterdam set to come to an end this summer.
"We are looking for a transfer for Tagliafico," agent Ricardo Schlieper is quoted as saying by the Daily Star.
"We have agreed with Ajax that he would leave this year. After having spent two-and-a-half seasons at the club, it's the ideal moment for it.
"If football goes back to being normal, a transfer could be done. There are clubs that are interested but we have to see how everything pans out with football and the pandemic.
"I will never mention a name of the club we are speaking with because it hurts the negotiations for us and the player."
Ajax are reportedly after €25m (£22.4m) for the 27-year-old, who made 24 Eredivisie appearances for the Dutch giants in 2019-20. body check tags ::
