It is believed United's executive vice-chairman Ed Woodward and head of corporate finance Judge agreed terms with Sanchez earlier this week, a deal that could pay the Chilean an astonishing reported the weekly salary of £500,000 ($693,000, 567,000 euros) before tax and when his signing-on bonus is factored in.
"If you ask me if I think he is coming, I think so, but I have no confirmation", the Portuguese told the BBC.
'I expect soon, or never, ' said Mourinho.
Jose Mourinho is confident his protracted pursuit of Arsenal forward Alexis Sanchez is nearing a conclusion at long last.
The coach said: "It's so close, so close, so close that if it doesn't happen, it's not going to happen".
However, just nine minutes after the restart, United broke the deadlock and it was Anthony Martial who slotted home with a perfectly placed venom. "We were not brilliant, but we were very good", said Mourinho. We are definitely a team that has improved, in my opinion.
"David (De Gea) today I don't remember anything important", Mourinho added.
"It's always hard but we are very happy because we win and they are three very important points for us, especially in this stadium".
"If you remember Van Persie, who also came from Arsenal and destroyed the Premier League by himself in the first season".
It may not have been thrilling, but it was the kind of disciplined performance that United need to keep delivering if they are to be in position to take advantage of any slip-ups from City.
Tottenham Hotspur, Liverpool and now United have collected all three points from Turf Moor in recent weeks, and Dyche's side have managed just eight goals in 12 games at Turf Moor, which is staggering for a team that is battling for a European spot at this stage of the campaign.
Burnley manager Sean Dyche has now seen his side fail to win for eight games but remains confident about their current form.
"When you get them there to the level and, after, they leave - of course that is the most painful and, after that, they do well for the other club".
