Arsenal 0-0 Crystal Palace
Leandro Trossard is getting booed every time he touches the ball by the Palace fans because of his connection with former club Brighton.
But another substitute Martin Odegaard almost crafts the first goal when his cross is met by the head of Gabriel Jesus, who had got ahead of marker Chris Richards, but can only head the ball wide.
Twenty minutes plus change before penalties.
