Michael Keane headed over the bar early on off a lovely set-piece cross from Kiernan Dewsbury-Hall, while former Villa star Jack Grealish, who created a game-leading five chances, saw a stinging volley saved by Martinez. James Garner set up Keane for another header, but the defender failed to find the target before Youri Tielemans nearly turned the ball into his own net off an Everton corner.
