According to VoetbalPrimeur, Kieft made these comments after Ajax's match against Atalanta, where Leonardo struggled to make an impact. The 23-year-old striker has been having a tough time, and Kieft believes that he is not yet the player that Ajax fans are hoping for. "The really good Leonardo, we haven't seen him yet," Kieft said. "It's like he's got a sack of potatoes on his back." Kieft pointed out that Leonardo is struggling to move quickly, doesn't ask for the ball deep, and has trouble getting away from defenders. He hopes that Ajax will see an improvement in Leonardo's performance soon. VoetbalPrimeur reports that Kieft's comments were made during an interview with Ziggo Sport.
