Pau Gasol has vowed to be more aggressive against the Celtics in Game Five on Sunday night, according to The Washington Post.

The Lakers will be looking to extend the series as Boston is just one win away from securing the 2008 NBA Title.

"I'll try to be as aggressive as I can, offensively and defensively," Gasol told reporters on Saturday.

"I've tried to do a good job defensively on (Celtics' forward Kevin) Garnett all series long, but I'll try to be a little more assertive on offense if I get the chance," he added.
