The 23-year-old felt his side had done enough to win Tuesday's game, only for Mario Balotelli's controversial late penalty to take away the victory.
Mario Balotelli's controversial late penalty snatched a point for the Rossoneri after Stefano Denswil's 90th minute strike looked to have earned the Dutch side a precious win.
“When we scored late on and Ricardo van Rhijn stopped a shot on the line, I thought we were destined to win," the 23-year-old defender told UEFA.com. “It’s a shame about the result because I thought we played very well. We dominated in the first half without really creating many chances.
“In the second Milan improved and we were no longer able to impose our game on them.
Ajax sits third in Group H with one point and trails behind Milan and Barcelona, with four and six points respectively.
