Keita had been frozen out since pre-season due to a contract dispute, but returned off the bench today and immediately scored.
“He was decisive," said Inzaghi.
“He had a good 40 minutes, is growing and needs to do more. He's got such quality and will give us a big hand this season. The important thing is we've got him back psychologically.
“In the first half we allowed Chievo very little, then made some mistakes on set plays and conceded the goal. At the end with a bit more determination we could've won.
“We were facing a side that runs a lot, so a draw here is fair enough. We need to do better and we know that. It was a good reaction to going a goal down."
