Belgium coach Marc Wilmots admits the feud between Liverpool goalkeeper Simon Mignolet and Chelsea's Thibaut Courtois has not been resolved.
The pair clashed in the media last season after Mignolet failed to hide his ambition to become Belgium's first choice.
Courtois, who was on loan with Atletico Madrid at the time, found those comments disrespectful given his incumbency.
Wilmots told Humo: "Okay, they're not friends but should they be?
"They have like pros, working well in training.
"That's the only think I desire.
"It doesn't matter who you are, as soon as that respect goes it ruins the atmosphere."
