Each time Alejandro Sabella was asked Monday about his lineup — and there were many attempts in different manners — he politely declined.

No hints whatsoever about Tuesday's second-round World Cup match with Switzerland, and no predictions about what style each team might play.

Sabella is preparing Lionel Messi and Argentina to attack a swarming Switzerland defense. The coach must decide whether to go with Ezequiel Lavezzi in a three-man front missing striker Sergio Aguero. An injured left thigh muscle forced him to leave in the first half of Argentina's 3-2 win over Nigeria last Wednesday.

The coach insists he might still be pondering his 11 players until midnight, and someone suggested he could announce the lineup then.

"I'm not going to say until the last minute. I think until this evening until around midnight I will think about the lineup," Sabella said before his team practiced at Itaquerao Stadium. "You can call me if you have my phone number, but I don't know if I will answer my phone at midnight."
