Benzema picked up a hamstring problem against Elche, and has missed the last three Real Madrid games. That said, he could be back to face PSG on Tuesday, though won't put his long-term fitness at risk.
"I've done a lot of hours of work and I feel much better," Benzema told the press.
"Now we have a training session to see if I can play, but I need to get more of that feeling of being on the pitch.
"I'm always going to fight for my team, if not I'd have stayed in Madrid, but I don't want to get injured anymore. I'll see in training. The most important thing is to be at 100 percent mentally, we have to recover and see in training, then we will decide for tomorrow's game.
"It's a complicated when you're off the pitch. I've been working at Valdebebas and at home to get back to fitness. In my head I'm ready but now I have to see physically. It's a big game and if I have to play tomorrow I'll give everything.
"The team has been able to win without me. I've done everything to get there. There's one training session and I hope to be well, but we mustn't take any risks because the season is very long."
