Despite the exchanges often becoming heated, Uruguay striker Suarez claims that any ill feeling towards Portuguese star Ronaldo is limited to club matches and not the global stage.
"When it comes to the rivalry with Ronaldo at club level that's a different thing altogether," he told reporters ahead of Saturday evening's clash at the Fisht Olympic Stadium.
"This is a World Cup and of course we're all defending and we're all working for our national teams, and that's the essential aspect. And everybody will try and give their utmost tomorrow as to prevail."
Uruguay and Portugal have faced off on two previous occasions, but never at the World Cup.
