Richard Cockerill claims Andy Farrell's England coaching role could conflict with his job at Saracens.
Farrell, the Saracens first-team coach, will support England interim coach Stuart Lancaster in the Six Nations.
He is set to work with players such as Chris Ashton, who has been linked with a move to Saracens when his contract with Northampton expires next summer.
"Clearly there's a conflict there," said Cockerill, the director of rugby at Leicester.
"Chris Ashton gets to work with the Saracens head coach for eight weeks. The clubs weren't consulted about that.
"We don't know the parameters of what he [Farrell] is doing or not doing."
Cockerill insists he has "no problem" with Farrell's coaching credentials, but is keen for the game's governing bodies to clear up any misunderstanding over his role.
"He's a quality coach; a really good bloke - [I have] no issues with any of that," Cockerill added.
"Premier Rugby and the Rugby [Football] Union need to at least clarify the situation on what Farrell does."
Cockerill has also confirmed that Tigers have agreed terms with England international Dan Cole.
"The detail of it's done but it just have to be signed off by both parties legally," he said.
"We produced Dan, he's come through our academy, he's a local boy and we have to keep those players and we've done utmost to do that.
"He's happy with that, we're happy with that and hopefully we can get that signed off very soon."
