Central defenders Harry Maguire and Yerry Mina have both been linked with moves to Old Trafford but Mourinho did not hold out hope of two additions before Aug 9. "I think I am not going to have two".
"The atmosphere is good, but if I was them I wouldn't come", said Mourinho.
Although worldwide players like Paul Pogba, Romelu Lukaku and David De Gea will be available for their first game against Leicester on August 10, they will not have played a game for three weeks and may well not have trained properly either.
Managers Jurgen Klopp and Jose Mourinho have clashed in recent days over spending, and it was Klopp's Reds who came out on top in MI with goals from Sadio Mane, Daniel Sturridge, Sheyi Ojo and Xherdan Shaqiri on debut.
Reinforcements, you mean players that I would like to buy, that's another thing. So don't look to this.
Manchester United manager Jose Mourinho has admitted that the club may recruit one more player before the transfer window concludes next month.
"This is not our squad". And I wait to see if it's possible to have one of these players.
"But when he saw that [Chris] Smalling in the warm-up was leaving, he decided by himself he did not want another kid on the pitch". It is not fair for Alexis, (Juan) Mata, (Ander) Herrera and the guys that are there. We are playing here just to try to survive and to have some not-very-ugly results. When it went, it was goodbye. 45 minutes Salah, 45 minutes Shaqiri, then 45 minutes Fabinho, 45 minutes another one.
"I'm focused on my training sessions and on the games".
Matic is the vital shield that protects Manchester United's defence and, last season, he made more interceptions (64), more tackles (42) and more recoveries (317) than any other United player- his 3,119 minutes played was also the most out of any of United's outfield players. Swiss forward Xherdan Shaqiri, a recent signing from Stoke, marked his debut with a brilliant bicycle kick that capped the scoring.
"In relation to this game, we have four or five players who are dead because they care for the team". I'm just keeping a positive mindset on everything and I just want to help the team win something. Gave him a lot of freedom, offensively playing natural, plus offering runs in behind, which is what he did, especially around the Sturridge goal. He is out for the start of the season.
New signing Alisson and fellow Brazilian Roberto Firmino will join the squad in Evian following their post-World Cup vacations.
