Norwich City have been unable to find a way past Charlton Athletic in the opening 45 minutes of their Championship tie at Carrow Road as the teams enter the changing rooms with the score level at 0-0.

The league leaders set the early pace to the game and Lewis Grabban came close to scoring his seventh league goal of the season inside three minutes, but Stephen Henderson beat the forward's shot away.

The 26-year-old showed his confidence once more just three minutes later with a 25-yard effort which whistled narrowly wide of the post.

At the other end, Charlton's striker Igor Vetokele tested John Ruddy with a strike from a similar range.

Russell Martin thought he had given his side the lead just before the break when he stabbed home a loose ball from a corner, but the referee blew up for a foul inside the box.
