Adebayor scored the opening goal and was then sent off as Tottenham crumbled and lost 5-2.
The former Arsenal striker told The Sun: "I completely understand my sending off changed the entire outcome of the game and I whole-heartedly apologise to my team mates, the manager and all the Tottenham fans for letting them down.
"But I must stress that my challenge was not malicious in any way whatsoever.
"I was genuinely trying to win the ball and probably stretched my foot out a bit too far in the heat of the moment.
"Nobody could have felt more devastated than me as I walked off the pitch. I so much wanted to help Tottenham win and thought for a moment that I'd actually set that win up when I scored, but football changes so quickly. One minute a hero, the next a villain."
