The Tottenham Hotspur midfielder has served a six-game suspension after the Belgium international was punished for violent conduct during a 2-2 draw with Chelsea at Stamford Bridge in April.
Dembele’s absence contributed to the north London side’s title bid collapsing after Mauricio Pochettino’s men failed to win their last four Premier League games.
The Lilywhites made an unbeaten start to the 2016-17 top-flight campaign ahead of Sunday’s clash against Sunderland following two victories and two stalemates thus far.
And the 28-year-old, who moved to Tottenham from London rivals Fulham in a £15m deal in 2011, is adamant that he has learned some valuable lessons from his lengthy FA suspension.
Dembele told Tottenham’s website:
“Yes, of course. You want to react in a different way next time, you need to keep your temper and just do the right things. It’s football, there are emotions involved but it’s something that’s behind me now and I don’t want to concentrate too much on that.”
Tottenham have beaten Crystal Palace and Stoke City in their opening four games, while Pochettino’s side played out draws with Merseyside duo Everton and Liverpool.
Spurs lost 1-0 to Ligue 1 side AS Monaco in the Champions League group stage at Wembley mid-week.
