New LA Galaxy striker Robbie Keane admits that the CONCACAF Champions League is not a competition he knows much about. The Republic of Ireland star kicked off his Galaxy career with a goal on debut in the 2-0 win over San Jose Earthquakes last weekend and is now preparing to take on Costa Rican club Alajuelense in Group A of the North and Central America's premier club competition.

The Galaxy meet the Costa Rican at The Home Depot Center on Thursday night and Keane admits he is not too familiar with anything to do with his opponents or the league as whole.

"Not too much, to be totally honest with you," he said when asked what he knew.

"I'm not sure about the team. Everything is, obviously, fairly new to me. As soon as I've played against these teams, been here for a little longer, I'll understand the teams I'm playing against.

"Sometimes it's nice going into games not knowing who you're playing against. You've got nothing to worry then."

And Keane, who joined LA from Tottenham Hotspur last week, said it was nice to get off the mark on debut as he plans to score plenty more goals for his new club.

"Any striker, you come to a new team, to get that sort of monkey off your back straightaway, it's always nice to score a goal on your debut," he added.

"Besides, people ask me the question: 'When you going to score?' It's still new, and, hopefully, I can keep going even more and get better and better and get stronger and stronger and score a lot more goals."
