The 30-year-old midfielder had spent two months on the sidelines until making his comeback last month with him so far being restricted to substitute appearances, including being a half-time replacement for Harry Winks in Spurs' 1-0 win against Crystal Palace at Wembley ahead of this current international break.
Dembele subsequently linked up with the Belgium national squad and featured for a half of the 3-3 friendly draw against Mexico on Friday.
And, looking ahead to the eagerly-awaited north London clash at the Emirates Stadium this weekend, he has put himself forward to be in boss Mauricio Pochettino's starting XI.
”My injury is much better," Dembele told Sky Sports. "I played 45 minutes in the last game so it is good. Of course, I want to be playing for the team and adding my value but right now I am very optimistic and feel good.
"For us every game is important but we know there is some extra vibe the for this kind of game, it’s important for us."
