Bayern winger, Franck Ribery is itching to get back into action and would like to start against Atletico.
The former France international came off the bench in the first leg, which Bayern lost 1-0.
But sat out the 1-1 draw against Mochengladbach after complaining of pains in his back.
However, the 33-year-old has stressed he is raring to go again when Bayern attempt to overturn the first-leg deficit.
“I am doing a lot better,” Ribery told Kicker.
“I have been doing some running and will resume squad training on Monday.
“I am ready for the game against Atletico. I am really looking forward to playing against them. I have to play.”
