Andre Agassi and Pete Sampras may not tour with the pros anymore, but their rivalry remains as viable as ever.

That was never more glaring than a year ago at a charity event in Indian Wells, when a seemingly verbal-volley exchange morphed into a tense, if not uncomfortable, confrontation.

Both players have expressed that their relationship remains amiable, but there will always be some animosity between them. Irrespective of their feelings toward each other, Agassi and Sampras go head-to-head at Madison Square Garden on Monday. We'll take all your questions and comments, starting around 9 p.m. ET.

And, tennis junkies, don't miss the appetizer to this showdown when Ivan Lendl faces old foe John McEnroe at 7 p.m. ET on ESPN3.com.
