Vicente Del Bosque was satisfied with Spain's performance in their 2-0 win over Republic of Ireland in New York, but thought they could have been more clinical in front of goal.
The European and world champions saw off Giovanni Trapattoni's side thanks to second half goals by Roberto Soldado and Juan Mata in what was their final friendly before they head to the FIFA Confederations Cup in Brazil, which begins on Saturday.
"We achieved what we came to do, nobody was injured and nothing bad happened in the run-up to Brazil," said Del Bosque. "We showed a good level of concentration and had most of the ball, but lacked the last pass.
"We did a good job on their counter-attack, so I'm leaving satisfied. We put in a good performance, we were superior and we should have won by more goals."
The coach stressed that both his side's friendlies in New York, a 2-1 win against Haiti and the Ireland match, had helped them prepare for the FIFA Confederations Cup.
"Physically we are better - and, in fact, better now than when we came. We head to Brazil in good shape. There is a good atmosphere in the team and the players are relaxed after such an intense season.
"We are confident, but we have to pay attention to all our opponents in the Confederations Cup, because they are all good sides."
Although Del Bosque said before the Ireland game that the team he put out against would be very similar to the one that would play in Spain's opening match of Brazil 2013 with Uruguay, he refused to confirm his starting line-up for the match on Sunday.
"Everyone in this squad is very good, every player is a regular starter for their respective clubs, and we have a very difficult task in choosing the best players from a great group," he said. "We have many options and they are all good ones."
