Chadli scored Tottenham's first goal of the night in their 3-2 win over Swansea with a fine volley, taking his total for the season to 10.
It was a strike that Dembele feels will raise his confidence and he was clearly happy to see his compatriot hit the back of the net.
“I’m happy for Nacer to get his goal as well," he said. "It’s a normal thing for us to try to have a good start and we try that every game. The team played well in general.”
Despite Dembele's kind words, Chadli still wasn't entirely satisfied with his performance, though, as he strives for continuous improvement.
The Belgium international proved his dedication by adopting a specialised training programme over the summer and he has clearly reaped the rewards of it in 2014/15.
The winger has gone from a player who looked lost during his first season at White Hart Lane, to someone who is one of Tottenham's main threats.
It has been a marked improvement, but Chadli is determined not to rest on his laurels now that he has established his place in the starting line-up.
“I have much better statistics than last season and I want to improve, I want to be a better player," he said to Tottenham's club website.
“I’ve played the last two games, played 90 minutes and I feel better and better every week and I think there is more to come. I want to score more than 10 goals and help the team to win games."
Chadli's prediction that he can go up another level is sure to excite Spurs fans and they will be hoping that he reaches new heights before the end of the campaign - helping them to a top-four finish in the Premier League.
