The ex-Tottenham star didn't feature at the weekend but says he will be fit to face Bayern for the second leg of a tie he insists is far from over
The Welshman has suffered from flu in recent days and was subsequently omitted from the starting XI for the first leg - which Real won 1-0 - but was brought on to replace Cristiano Ronaldo for the final 17 minutes before being rested for los Blancos' 4-0 league win over Osasuna at the weekend.
The former Tottenham Hotspur winger says he is fit and wants to play against the German champions, insisting his side will give their all in what is a crucial tie.
Bale told reporters: "I feel good. I have had a few days training. I'm hoping to play tomorrow and looking forward to it.
"It’s been a good season so far but there is still a lot of work to go. We haven’t spoken too much about the game, but we know it’s a massive one with a lot at stake. We are ready to give it 100 per cent; our best shot.
"I don't feel like we've qualified for the final yet. We have a very hard game to come against Bayern. We are looking forward to it. We like to attack but we need to know how to defend too.
"We are confident. When you arrive at a club like this you feel the expectation, but there is a great atmosphere within the group. We wanted to win the Copa del Rey and we did so.
"We want to do the same in the Champions League. We are eager to play against the best teams and to win titles.
"We will look to play good football as we always do. We are not the type of team that comes out with the idea of playing extremely defensively."
Madrid travel to Germany with a 1-0 lead from the first leg as they hope to secure a place in the final against either Atletico Madrid or Chelsea.
