Tottenham midfielder Eriksen was widely linked with a switch to Manchester United this summer.
The Denmark international was reportedly offered to the Red Devils in the final days of the English transfer window but a deal could not be struck.
Eriksen is currently in the final year of his Spurs contract and has publicly expressed his desire to leave.
United boss Ole Gunnar Solskjaer personally spoke with Eriksen about the move but was told the 27-year-old had his heart set on a move to Spanish giants Real Madrid.
United were also reportedly concerned that Real had persuaded Spurs to offer Eriksen to them in a bid to help force through a move for Paul Pogba.
Zinedine Zidane would reportedly prefer recruiting Pogba ahead of Eriksen, with Los Blancos making an unsuccessful bid for the Frenchman this summer.
The offer of £27.4million plus James Rodriguez was rejected by United who decided they would rather keep Pogba instead of signing Eriksen and then letting the former leave for Madrid.
Now, with the English window closed and Eriksen no longer a priority for Madrid, the playmaker looks set to stay in north London.
But Eriksen might have joined United earlier in his career, according to the Manchester Evening News.
The club scouted the Dane who was said to be keen and Ferguson even spoke to the player’s agent, reportedly expressing his admiration but stating he needed to watch the player more closely.
United ended up opting to sign Shinji Kagawa from Borussia Dortmund instead.
United were also interested in bringing Toby Alderweireld to Old Trafford earlier this summer, with the centre-back having a £25m release clause that could have been triggered before July 25.
However, they instead opted to make Harry Maguire the world’s most expensive defender in an £80m deal with Leicester.
United were supposedly wary of engaging in transfer talks with Spurs chief Daniel Levy, a notoriously tough negotiator.
The two clubs last did business more than a decade ago when Dimitar Berbatov joined United in 2008.
Speaking about the negotiation process, legendary Red Devils manager Ferguson described dealing with Levy as “more painful than my hip replacement”.
