Sunderland’s defensive problems are due to players struggling to communicate in the same language, according to Patrick van Aanholt.
David Moyes’ side are yet to win this season and have lost three of their opening four matches of the Premier League campaign.
The Black Cats were beaten 3-0 by Everton on Monday and left-back Van Aanholt admits he is finding it difficult to communicate with team-mates.
Sunderland’s starting XI at the Stadium of Light featured eight different nationalities, including recent arrivals Javier Manquillo and Papy Djilobodji in defence.
“They need to adapt,” said Van Aanholt. “We help them in training and try to speak the same language because it’s very hard to understand them on the pitch.”
The 26-year-old also expressed his disappointment at the way the team responded to Everton going ahead.
“We were in the game, created chances and at half-time, everything was OK,” he added. “But after they scored the first goal, our heads went down and that was it.”
