Mourinho has repeatedly expressed a desire to bring in additional signings throughout pre-season with a central defender top of his list.
Mourinho guided Manchester United to their best Premier League finish since the retirement of Sir Alex Ferguson in 2013, but the 55-year-old coach has insisted that he wants to sign two more players before the end of the transfer window.
"I'm not confident, I'm not confident and the market closes today so is time at least for me to stop thinking about the market because the market will be closed".

"They returned on Monday, trained Monday, Tuesday, Wednesday and today, so you can imagine that they are not really fit and ready but we have needs", said the manager. The tactics to be changed in Championship Manager you can just press a button.
"It looked like I was saying something absolutely out of order, something insane, I repeat: Pre-season hard when you don't have your players to work, that's as simple as that".
