Elmohamady is set to start against Bolton
"His English isn't coming along too badly, and he gets his point across when he needs to," the Nigerian defender was quoted as saying in the Sunderland Echo.
Elmohamady is taking courses in English, as he wasn’t familiar with the language when he first came to England on a season-long loan at Sunderland.
"You don't really have deep and meaningful conversations during the game anyway. As long as he gets his point across and he understands what we're trying to say to him, then it's fine,” Onucha added
The 23-year old international winger made his mark in the Premier League and enjoyed a run of starters in the early part of the season before coach Steve Bruce decided to give him a break.
The former Enppi and Ghazl El Mahala player is expected to be included in Bruce’s starting XI when Sunderland host Bolton on Saturday.
The Black Cats are suffering from an injury crises in defense as Anton Ferdinand, Michael Turner and Titus Bramble are on the sidelines.
Onuoha will play alongside Ghanaian defender John Mensah in the centre of defence while Elmohamady is set to play at the right-back position.
"I've been told he's the Egyptian national right-back, so he knows what he's doing. He's quite direct as well, so it's good to have him down that right-hand side," Onuoha concluded.
Elmohamady made few appearances at the right-back as Bruce preferred to free him from his defensive duties and give him more license to attack as a right or left winger.
