Henry and Grella engage in a fiery MLS discussion

The pair were assigned to cover Liverpool's highly anticipated Champions League matchup against AC Milan.

When speaking about the current standard of Major League Soccer, Henry went straight for the jugular.

“I played in the MLS, I thought the American-based players in the MLS were better than the American players now in the MLS,” Henry said, before adding “answer that one” to Grella.

Grella had his own comeback, stating with a grin on his face: “I know you played in MLS, I replaced you!”

Henry fired back: “Don't go there! You didn't replace me. You won't win that argument.”
