Bob Peeters has hailed his sides performance at Carrow Road, with the Addicks winning 1-0.
An 86th minute Johnnie Jackson goal stole the three-points for the Londoners, and prevented Norwich moving clear at the top of the Championship table.
Despite the Canaries being on a run of eight games without defeat, having only lost on the opening day of the season, and dominating the home tie - with 61% of the ball and 15 shots to Charlton’s four - Bob Peeters decision to switch away from the 4-4-2 and to a 4-5-1 for the first time this season paid off.
An incredible defensive performance was the platform from which Jackson left it late to net the winning goal, and secure a first win in four for the Addicks, leaving many to label the performance as ‘smash-and-grab’.
Peeters feels as if calling the results a ‘robbery’ is acceptable, although he was keen to point out that defending is just as important as attacking in football.
Speaking to the official Charlton website after the game, the Belgian said: "If you play away at Norwich, a team that wins four games in a row, and one that calls itself one of the favourites to win promotion then it is a good result to win it 1-0," said Charlton's Head Coach.
"If you compare their budget to ours then it already says a lot. Our boys worked very well. We had to do it without Chris Solly and Johann Gudmundsson, two important players, and if you can then win 1-0 it might be a robbery. We defended well and it football it is not only attacking but defending and sticking to the game plan.
"Away from home you need to keep it tight and if you get a chance you need to take it.”
Charlton frustrated Norwich for much of the game, and the Addicks head coach believes that his players received extra motivation when he showed them a local paper that was suggesting the Canaries would walk the tie with ease - securing a 3-0 victory.
Peeters added: "Norwich are a top team but I showed my players a local newspaper that had a prediction for them to win 3-0.
"I said if we stick with the game plan, press them in midfield and close the angles then they are going to struggle. They had one really good chance when Joe Gomez was struggling with his ankle and that was it.
"I said at half that they would get tired, the crowd would get frustrated because they couldn’t handle our game plan at the end we knew the spaces would get bigger and if we get one or two chances then we need to punish them. The first chance with Bulot and the second we did that with Jackson."
