Luis Enrique issued a strong defence of Alvaro Morata after a 0-0 draw with Portugal that saw debutant Aymeric Laporte impress the Spain boss ahead of Euro 2020.
The 2012 winners were unable to find a way through against the reigning champions as the two neighbouring nations met in a friendly fixture as part of their preparations for this year's tournament.
However, Spain saw Morata fail to convert a glorious late chance at the Wanda Metropolitano, his attempt when clean through hitting the crossbar.
It was one of four shots by the striker during proceedings, of which only one ended up on target. Still, he did make two key passes and, despite the crowd getting on his case following the miss, his head coach was more than happy with what he saw.
"I am not worried about it," Luis Enrique said when asked about the 28-year-old.
"The last play saw Morata kill himself to pressure. He has been a constant nuisance for the Portuguese, doing an incredible job, and in the 90th minute he is able to make a 40-metre action, fool the goalkeeper and then has bad luck when hitting the crossbar.
"I think that's something to be applauded. I have seen him very well in terms of his morale, he is already used to it [the criticism]."
There were also whistles at full-time after the hosts failed to capitalise on their dominance. Spain had 65.7 per cent of possession which led to 10 attempts, albeit Portugal goalkeeper Rui Patricio only had to make two saves.
"I haven't seen anyone whistle at me. I do not care. Yes, it bothers me that it is done to the players," a defiant Luis Enrique said.
"Everyone can do what they want, but I just found out now. I understand my role, I know what it means to be a public figure.
"But people praise me and even blow me kisses, so I feel loved and in Madrid I am delighted."
Laporte was clearly one of the positives to come out of the fixture for Spain, the Manchester City defender combining with fellow centre-back Pau Torres to keep Cristiano Ronaldo quiet.
After Portugal had just one on-target attempt during the contest, Luis Enrique said: "I have seen it as expected, very good. It is not common and normal to have two left-sided central defenders, but I have played many years with right central defenders and it does not surprise anyone.
"It is difficult to find two left-sided central defenders of this quality. They have been exceptional, dominating in the air, in passing the ball, putting pressure on the Portuguese forwards. They were outstanding."
