Earlier this week, United announced that they had agreed to keep Shanghai Shenhua forward Odion Ighalo at Old Trafford until the start of 2021.
Given the financial implications of the coronavirus pandemic, that could have led to United cooling their efforts to sign Sancho, who could cost in the region of £100m.
However, the Evening Standard claims that the Premier League giants continue to prioritise the addition of the England international.
Although the report hints that sales may have to be made before next season, it says that the 20-year-old is still at the top of United's shortlist.
Sancho has enjoyed an outstanding campaign, contributing 19 goals and 18 assists from just 35 outings in the Bundesliga and Champions League.
