The former Sampdoria midfielder was thrilled to see his team-mate recover his nerves of steel from the spot in the final moments of the Champions League clash with Ajax
The 23-year-old missed his first-ever penalty in senior football in the 2-1 loss against Napoli last month, but he swept home from 12 yards in the dying moments at the Amsterdam ArenA to salvage a point for the Rossoneri.
And Poli was thrilled to see his team-mate keep his cool from the spot, telling the club's official website: "I don't think Balotelli was nervous. He took the penalty well.
"In the first half Mario found the going a bit hard like we all did."
The midfielder was pleased with the way his side rallied in the second half to up their game and secure a 1-1 draw in Amsterdam after going behind to Stefano Denswil's late goal.
"It was a tough first half but we did well in the second half. We attacked them harder in the second half and things went better. We came close to scoring a few times."
Milan sit second in Group H with four points from two games, with Ajax occupying third place with one point.
