This new deadline which closes before the season starts has really ramped up the pressure on these transfers which means we could see a whole host of panic buys as clubs look to add to their squad before the Premier League season starts this weekend. The way in which United are being talked about this pre-season, it's as if they've got a load of bums playing for them.
Asked whether he he believed there would be any movement in or out of Old Trafford on deadline day, Mourinho replied: "The information I have is no".
'I said during pre-season - it looked like I was saying something absolutely out of order, something insane - but I repeat: pre-season is hard when you don't have your players to work, it's as simple as that'.
Sources told ESPN FC on Wednesday that while United were still pursuing a centre-back, but the chase has become problematic during the final hours of the window.
Jerome Boateng was another option but Bayern Munich have not been keen to sanction a loan move.
Mourinho heads into the Leicester match with a hefty injury list, including key midfielders Nemanja Matic and Ander Herrera, while a host of other stars of only recently returned from their break after World Cup duty.
"The list that I gave you before of the injured players is an important list and today after training I will speak with that group of players (back from the World Cup) because everybody is different, physically and mentally, to see how available they feel".
Marcus Rashford, Phil Jones, Victor Lindelof and Romelu Lukaku made slightly early returns so could be involved on Friday, perhaps helping to boost the mood of a manager who has looked downbeat for much of the summer.
"I will have to focus on the players I have in relation to the first three matches, because after Spurs there is an worldwide break and I have a couple of weeks to recover people and prepare them better".
"They returned on Monday".
The Red Devils coach has cut a sullen figure throughout pre-season with the former Chelsea boss unable to hide his dissatisfaction with Brazil worldwide midfielder Fred being his sides only high profile signing.
