The Republic of Ireland international returned from injury to help Galaxy to a 3-1 victory over the Italian champions at Dodger Stadium
The 33-year-old Republic of Ireland international had been ruled out of action for three weeks after suffering a hip-flexor strain but made a goalscoring return to action last night.
Entering the fray in the second half, Keane set up the decisive winning goal for Landon Donovan before capitalising on a poor pass from Andrea Pirlo to steer the ball past Marco Storari in the closing stages of the game to make it 3-1.
"For me, it was about 45 minutes and getting my fitness right," Keane told reporters after the game. "I wanted to be sharp for the most important game, which is next Sunday against FC Dallas."
LA Galaxy head coach Bruce Arena also took time to praise the Irish striker, who was instrumental in the victory. "Robbie played well," he said. "He's been out three weeks and our plan all along was to give him some minutes."
Meanwhile, Everton defender Seamus Coleman says that he is not too disheartened after the Toffees suffered a 2-1 defeat against Real Madrid. The Republic of Ireland international supplied the cross for Nikica Jelavic's second half goal, but could not do enough to overturn the deficit.
"It was great experience," Coleman told the club's official website. "As a player you want to play against the best in the world and Real Madrid are certainly that.
He continued: "It was good to play a part in the goal but it's about the team and we didn't get the result. But there are positives to take.
"That is what it's all about, the Premier League, and preparing for it and we are looking forward to the first game of the season."
