The 35-year-old sustained "significant knee ligament damage" during United's 2-1 Europa League win over Anderlecht in April, which required surgery and brought an end to his season at Old Trafford.
The Manchester United boss added: "We open our door for him to recover with us, and at the same time let's make a decision that makes us all happy". "It's the same with Morata, we have to respect the player, the club, the owner, the manager".
"I would not like to be in [chief executive] Ed Woodward's position negotiating because everything is really hard", Mourinho told reporters ahead of United's first pre-season friendly against MLS side LA Galaxy. I don't want to say any names, because I don't think it is correct.
And Mourinho has suggested the La Liga side priced Morata out of a move to Old Trafford.
'Arsenal won a competition, we won two-and-a-half, I like to say. "Personally, if I had to play one man up top and I was a United fan, I would go [with] Rashford". The French midfielder, Romain Alessandrini has been one of the few bright spots on the team and should be a key player to watch in this game. "And we didn't arrive at an agreement with Real Madrid".
"Yes, we have had interest, that is obvious and it's public". We will not be the ones who put a price on a Real Madrid player.
The Red Devils will also be hoping to mount a serious title challenge next term after they finished sixth in the Premier League table.
