Manchester United will demand over £35million for Henrikh Mkhitaryan should clubs enquire in the coming weeks, Daily Mail reported.
According to the source, United's valuation could scupper the prospect of a January deal. Inter need to sell to fit within Financial Fair Play guidelines.
Mkhitaryan is a popular figure at United's training ground but has fallen out of favour with coach Jose Mourinho after some lacklustre performances and a disagreement over video analysis following the defeat to Chelsea on November 5.
United beat Arsenal to sign the Armenia captain for £27million in 2016.
