But the Old Trafford club remain adamant they will not meet Borussia Dortmund’s £108million asking price for the England forward.
United have held constructive talks over the agent fees being demanded by Sancho’s representative Emeka Obasi.
That has given rise to fresh optimism they will be able to secure a deal for Ole Gunnar Solskjaer’s top target during this window.
But there are still significant obstacles regarding Dortmund’s valuation and Sancho’s salary that is forcing United’s hierarchy to proceed with caution.
While there is a strong belief the England international wants to join Solskjaer’s revolution, United are adamant they will not overpay in a market hit by Covid-19.
They believe transfer prices have been depressed by around 20-30 per cent.
And despite their determination to land Sancho, they remain prepared to move on to alternative targets.
