Carlos Tevez has admitted he knew that he was offside in the run-up to his opening goal of Argentina's 3-1 victory over Mexico on Sunday.
The Manchester City striker scored two goals in Diego Maradona's team's victory, with his second undoubtedly proving his quality with a fine finish.
His first goal, which gave the Argentines the lead midway through the first half, was a cause for controversy as Lionel Messi pounced on a rebound to chip the ball to Tevez to head in, despite standing in an offside position.
Replays on a big screen in the stadium showed footage of the goal, including Tevez's position, leading to mass complaints by Mexican players appealing for the goal to be disallowed.
Italian referee Roberto Rosetti and his assistants however waved away the claims, with Tevez stating that he was 'selfish' to not own up to the decision.
"At first I thought he (Rosetti) was saying that it was not a goal, then I saw the signal and I started (celebrating) and I was happy," Tevez said.
"I know I was offside, I know it was selfish but as long as they say it was a goal it's OK for me and the team.
"The team is growing in every single game, in every game it is getting stronger and we can win and that is the important thing. We can win the World Cup."
Tevez's team-mate Joan Gutierrez was also positive about his team's performance, claiming that they had the momentum required to be able to win the World Cup, as well as praising Tevez and Maradona for their contributions.
The Argentines now face Germany, who impressed in their 4-1 mauling of England, in the quarter-finals of the tournament on Saturday in Cape Town.
"It was a tough game but the national team of Argentina did a very good job, we scored three goals, we could have had more," said Gutierrez.
"Tevez was fantastic, so was the whole team, we have a very good group with incredible quality.
"We want to take on board all the experience of (coach) Diego Maradona. He won the World Cup (in 1986) and that is the experience we want to take from him.
"Germany is a very good team and it will be a very tough game, but if we want to be in the semi-final we have to win this game."
The controversy regarding Tevez's goal and the fact that it was displayed on a video screen brought an immediate reminder of events during Germany's victory, where Uruguayan official Jorge Larrionda failed to spot Frank Lampard's shot clearly cross the line when the score was 2-1 to Germany.
Despite mass calls for video evidence, the Newcastle winger insisted that it was inevitable for a referee to miss an incident during the game.
"This is football - we saw on the television that it was offside, it's very tough for Mexico but we can do nothing. Sometimes the referee can make a mistake," Gutierrez added.
"The referee can make a mistake because things can happen in one second. The game is very fast, so we cannot say anything (bad) about the referee."
