Everton manager Marco Silva believes Bernard is ready to make his full debut following an impressive substitute appearance against West Ham last weekend.
The Brazilian came off the bench just before half-time at Goodison Park and was one of the few high points in Everton's 3-1 defeat.
Bernard is still working his way up to full match fitness following a summer move from Shakhtar Donetsk, but Silva could start him against Arsenal on Sunday.
"Bernard can help with everything we need." Silva said.
"He is ready to give 100 per cent, even if he is not yet in his best physical condition, which is normal because he did not play since last March.
"In his first 50 minutes he did well, he had a good impact in a difficult moment in the match. He is a different profile from the other wingers in our squad. A quality player and he will help us. If I need 90 minutes, he is ready for what I need."
Silva, who guided Olympiakos to a 3-2 Champions League victory at the Emirates back in September 2015, has vowed his team will look to play on the front foot against the Gunners.
"It is our way," he said. "We cannot change everything because we play against a strong side. They will make us in some moments do things we don't like and create problems for us.
"But when we have the ball in our offensive transition, in our offensive organisation, we have to keep our football, our way to play, to create problems for them."
