Ferguson has already spent in excess of £50m during the close season following the arrivals of Ashley Young, Phil Jones and David de Gea.
Reports had suggested that United chief executive David Gill has been in Milan thrashing out a deal with Inter and Sneijder (right), but United have since confirmed that Gill was heading to Zurich for a European Club Association meeting.
Ferguson added: “I keep reading about this, there’s absolutely nothing at all to that [reports of United’s interest in the player. First of all I don’t think Inter are prepared to sell him anyway.
“You get conjecture and you get speculation every week in newspapers unfortunately. And we have to answer these for some reason – why, I don’t know, but we have to find a reason without adding insult to any particular club, or embarrassing any player.”
