Keane claimed Thomas Partey lacks “leadership skills" after Ghana's dramatic loss to Portugal.
He said on ITV: “Well he's having a very good season. He's settled down, he had a lot of injury problems when he first went to Arsenal.
“He's got a big role here because there are some inexperienced players around him. I'm still not convinced he's got those leadership skills.
“But a very good player and he'll have a big part to play today because there's a big responsibility, particularly in the middle of the park, of course a huge position on the pitch.
“He's had a good season, he should be confident, but it's a big challenge for him in the middle of the park to help the players around him."
