The Welshman is unsure whether Carlo Ancelotti will pick him but he is excited to play his part in one of the biggest derby games on the planet
The Welshman came off the bench with 25 minutes to go to feature in the Blancos' 2-1 victory over Juventus in the Champions League in midweek as he continues his recovery from injury.
Head coach Carlo Ancelotti has claimed that the €100 million summer signing could feature from the first minute at Camp Nou, but the 24-year-old remains in doubt as to whether he will be named in the starting line-up.
"I am not too sure if I'll start," he told Sky Sports. "I have had a few minutes this week and I have had a good week's training as well so I think I am fit enough and it is up to the coach now whether I play from the start or I am on the bench.
"I am sure it will be an amazing experience. The most important thing is we try to win the game and get the three points and I am looking forward to it just like everyone else is."
Bale has lauded Cristiano Ronaldo for the help he has been given from the former Manchester United forward since his arrival in Spain, and is working hard to put his recent injury woes behind him with the help of his Santiago Bernabeu team-mates.
"Ronaldo has been absolutely amazing with me," the ex-Tottenham man added. "He has given me a lot of confidence and I think he has been in the position before so he has been great with me.
"Everybody has been great in the changing room and I felt very settled straight away and I am just looking forward to kicking on now.
"I am enjoying everything about Real Madrid at the moment, obviously it was a bit disappointing to get the injury but that is behind me now and I just want to kick on now, play as well as I can and do my best for the team."
