Sporting boss Jorge Jesus has insisted no opponent will play in the Bernabeu like his brave side did in Wednesday's Champions League Group F opening loss.
Late goals from Cristiano Ronaldo and Alvaro Morata overcame a 47th-minute strike from Bruno Cesar to give the home side a dramatic last-gasp victory.
And the Portuguese manager expressed pride in his team's performance after the match.
"We know what qualities we have no matter who we play and we showed tactical discipline. We were excellent until the 88th minute and the Madrid substitutes helped change the game. When new players came on we lost a bit," Jesus said.
Sporting dominated Real for long stretches on Wednesday, and in that Jesus took special satisfaction despite the disappointing defeat in the end.
"I think we played a great game, but we need a bit more experience. The Ronaldo goal was great, he's the best player in the world and that happens. It shouldn't have been able to, but it happened.
"No side will play here in Madrid as well as we have done. They didn't have a single chance in the first half, but there's a reason they're European champions.
"They have that mentality and reputation and changed the game in two minutes. We lost in a game in which we played with great spirit. We didn't deserve to lose.
"It presents a lot to think about. If we'd have won or drawn it would have been a different outlook but as we've lost it's different.
"We played a great game but we didn't get any points and the whole group stage of competition is that we have to get points."
