Charlton Athletic and Millwall have failed to break the deadlock in the first 45 minutes of their Championship encounter which is level at 0-0.
Igor Vetokele came close for the hosts in the opening five minutes, but the in-form striker glanced Jordan Cousins's cross narrowly wide.
Millwall didn't allow the home side any time on the ball though, as their pressing game forced the Addicks into a number of mistakes.
Martyn Woolford fired wide from distance in the 11th minute before Ed Upson saw his header parried away by Nick Pope as Millwall became more confident as the first period progressed.
Andre Bikey should have headed the hosts in front a minute before the break, but the central defender nodded wide of the mark from Johann Berg Gudmundsson's corner.
