Portugal head coach Fernando Santos insisted there was little difference between a win and a draw against the Republic of Ireland as World Cup qualifying would still be decided against Serbia.
Santos' side were held to a goalless draw in Thursday's clash with Ireland, who have just one win to their name in World Cup qualifying.
The Euro 2016 winners had previously embarked on a five-game winning run across all competitions, scoring 16 times, but could manage just three shots on target in Dublin.
The stalemate leaves Portugal and Serbia both on 17 points with one game remaining and the top two will meet in Lisbon on Sunday in Group A's winner-takes-all decider.
Asked if he was happy with the result, Santos told RT3: "Naturally. In terms of qualification, winning 5-0 or drawing here was the same thing.
"Of course, I would have preferred to win 5-0, but the result is positive. Serbia have to play in our stadium to win the game.
"Obviously we wanted to win, we didn't want to draw, that's not what we came here for. They're a very aggressive and very physical opponent.
"In the attacking organisation, we let them create danger. The players tried but we always had difficulties – they were quick to close spaces."
Santos, who insisted he was "convinced" Portugal would still qualify, left out the likes of Ruben Dias, Bernardo Silva and Joao Cancelo for the visit to the Republic of Ireland.
He will also be without Pepe against Serbia after the centre-back was dismissed late on for two bookable offences.
Asked for clarification whether he had spared players to avoid yellow-card accumulated suspensions, Santos added: "I saved them because you never know if the players are conditioned or not.
"I wanted to have Pepe for the game, but I'm going to sleep well. We'll find the right players [for the Serbia game]."
