Adebayor was shown a straight red card after a tackle with Santi Cazorla in the 18th minute.
â€śIâ€™m sad, Iâ€™m disappointed,â€ť Adebayor told the Spurs website.
â€śI scored my first goal of the season and I was so happy, but then it was a 50-50 ball, I went for it and the referee decided to give me a red card.
â€śIt was difficult to let the team down like that.
â€śWe had to play 70 minutes without me, with 10 players, and especially at Arsenal you know how difficult the game will be.
â€śEven with 10 men the team showed character. They tried to come back and it was a tough one. We have to take the positives out of the game, get our heads right and keep going.â€ť
He added: â€śI tackled for the ball, it was 50-50 and unfortunately, Cazorla touched the ball before me and there was contact between him and myself, thatâ€™s for sure.
â€śThatâ€™s football. We all have to learn from our mistakes and especially me, after scoring, I donâ€™t have to tackle. I donâ€™t know why I did that. I just wanted to help my team-mates, I wanted to win the ball back for them, but it went the wrong way.â€ť
