Eriksen left Tottenham last week for Inter.
Spurs were willing to offload Eriksen to Manchester United for around £50m in August and the 27-year-old revealed he held talks with the Old Trafford club.
“It was never really likely," Eriksen told BBC Sport. “We did speak to them, of course, and we did hear what was possible and what wasn't possible. But, in the end, me personally, I wanted a new challenge. To stay in the Premier League would have been an easy solution.
“Of course, staying at Tottenham would also have been a solution but, for me, it just came down to wanting to try a new challenge in a new country. Once Inter came up it really wasn't a difficult choice."
