Denilson, 19, made it an all-Brazilian pairing for Arsenal in central midfield with Gilberto Silva on Wednesday night and has settled well into the Gunners squad after his move from Sao Paulo in August 2006.
Having come up through the international youth ranks, he now hopes to get a chance with the senior team.
"Hopefully (Brazil coach) Dunga will look at this game and see that we can play together," he told Arsenal TV Online. "I am working very hard and I hope next season I can get in the national side. I am progressing well."
After Theo Walcott's late equaliser against Spurs, Arsenal remain very much still in the tie but they must score at White Hart Lane in a fortnight to have any chance of making it to Wembley and a second successive appearance in the Carling Cup final.
The Gunners have not lost to their north London rivals now in some 21 clashes and came back from 2-0 down in the first away leg of last year's semi-final.
Denilson said: "It will be a good experience for us - but we have a good team and we must show that now. The memory of last season will help us.
"I am very proud of the team. The Carling Cup is very important to everyone and we must now focus on the game against Tottenham.
