The Tottenham midfielder made it clear last summer that he felt it was time to leave the club.
Real Madrid were the most-linked to Eriksen and appeared his likeliest destination, but the Spanish giants prioritised other signings such as Eden Hazard.
Zinedine Zidane was also reportedly unsure of the player and it's understood that he would prefer the signing of Paul Pogba from Manchester United.
United themselves were reported to have enquired over the summer but didn't make a formal approach for the Dane.
It's understood that Spurs will ask for £40m if clubs want to sign Eriksen immediately, which is much less than he'd go for on a longer contract.
The 27-year-old is a free agent next summer and therefore can negotiate freely with prospective clubs in January under the Bosman ruling.
However, United will have to put together an attractive proposal because a host of Europe's elite clubs are reportedly preparing their own.
It's reported that Real Madrid have reignited their interest and are joined by La Liga rivals Barcelona.
