Redfearn inherited a first-team squad that includes six Italians, a Brazilian, a Slovenian, a Paraguayan, a Dane and a France-born Senegalese when he replaced Darko Milanic at the end of October.
But the former academy manager, bidding for his second win as permanent boss at Blackburn on Saturday, said nothing was getting lost in translation on the training ground.
"Surprisingly no," he said. "To be fair to the overseas lads, their English is quite good, I have to say. "They've really bought in to what we're doing and their work ethic and the way they want to train and play is good anyway.
"So it's not so much a problem the language barrier." Leeds are chasing only their second league win on the road this season - they have not beaten Blackburn in over 10 years - and Redfearn wants his players to be braver on the ball.
"I want to make the players proud of what they're doing," he added. "I want to give them ownership. "They've got to take responsibility because it's alright us sat here talking about it, but it's them who have to go out and do it."
