Spurs were brushed aside 4-0 by the Spanish giants mainly due to Peter Crouch's 15th minute sending off but Lennon, who was withdrawn from the game ahead of kick-off, had a rant on his Twitter account saying he feels like a scapegoat.
However, Redknapp has made it quite clear that the club is right behind the winger and have laid no blame on him for their disappointing performance.
"No one is blaming Aaron for not playing. He's been fantastic for us. I've got no problems with the kid whatsoever," Redknapp told talkSPORT.
"I was sitting in the dressing room before the match, looking at his face. He's normally chirpy before he goes out and I looked and he didn't look well.
"I had to make a decision. It wasn't Aaron's fault. He didn't bottle anything. The kid wasn't well. No one's made him a scapegoat."
