The Egyptian was in line to make his first appearance for Spurs in more than a year, coming on as a second-half substitute in last weekend's FA Cup win over Wigan.
But Spurs fans sounded their protests against Ghaly's introduction, forcing manager Harry Redknapp to call the 27-year-old back to the bench.
"I made one mistake when I took off my shirt when I was substituted, I have explained in the past," he told skysports.com.
"It was because of frustration with my performance and not the manager, I apologized to the manager immediately and I also apologized to the Spurs fans on the club's official website.
"I want the fans to know that I am truly sorry for what happened at that time but that was in the past and this is now.
"If the manager puts me on the pitch I promise that I will give everything for him, for the team and for the fans.
"I want them to judge me on my performance should I get the chance and not something which happened in the past and which I cannot change."
Redknapp Impact
Ghaly hailed the impact Redknapp has left on the team after taking over from Juande Ramos last October.
The former Ahli schemer, who was determinant to leave Spurs in recent months, revealed how his attitude towards the club has changed since Redknapp's arrival.
"Everybody here enjoys training, it is hard work but enjoyable," he said.
"There is a good team spirit and togetherness amongst the squad. The manager has made a big impact on everybody since taking over.
"All I can do is continue to work hard and if the manager asks me to play I will be ready.
"After the fans reaction last week it was tough for a couple of days but the manager, Clive Allen and my team-mates have been great with me."
Ghaly is included in the squad for Tuesday's Carling Cup semi-final first leg against Burnley at White Hart Lane, which may well be his long-awaited season debut.
