LANDOVER, Md. -- The rivalry between the New York Giants and Washington Redskins is heating up.

After the Redskins edged the Giants 17-16 in a pivotal NFC East game on Monday night, Washington owner Daniel Snyder was reportedly overheard expressing his hatred for the defending Super Bowl champions.

As the media was allowed into the Redskins locker room earlier than usual, Snyder shook hands with a team employee and said "I hate those m-----f------," according to USA Today.

The Redskins were fired up for their Monday night game against the Giants, using critical comments from Giants co-owner John Mara as motivational fodder leading up to the game, sources told ESPN NFL insider Adam Schefter.
