Diego Chara helps create a special Timbers-Sounders match poster showing the "arm wrestle that never ends"

Ahead of this weekend's Heineken Rivalry Week fixtures, MLS tapped into the players' creative sides to develop a series of match posters that speak to each rivalry. Our own Diego Chara offered up his thoughts about Portland-Seattle. From there, they brought their ideas to life with the help of artists Noah MacMillan.

Chara offered up a perfect metaphor for the Portland-Seattle rivalry: "An arm wrestle that never ends." As someone who featured in the first-ever MLS meeting between the sides, the Colombian is no stranger to battling Seattle in central midfield (or scoring the rare, incredible goal).

Head over to MLSsoccer.com for a look at all the rivalry week match posters and be sure to watch Timbers-Sounders match presented by Providence Health & Services on Sunday at 7:30pm PT on ESPN2 with a special pregame broadcast beginning at 7pm PT.
