Charles De Ketelaere, Atalanta's Belgian forward, heads into the club's Conference League play-off second leg against Hapoel Tel Aviv having trained insufficiently to be considered a reliable option, with Maurizio Sarri confirming the situation in his pre-match press conference on August 27.
The timing matters. Atalanta are a club in transition — new coach, new system, new competitive calendar — and De Ketelaere's unavailability for selection, even in a European qualifier, complicates Sarri's ability to assess his full squad. A manager building a 4-3-3 structure needs to know what his attacking pieces can do under pressure. A forward who cannot train consistently cannot answer that question.
De Ketelaere is 25, an age at which a player of his profile should be entering the most productive stretch of his career. His Serie A season has barely begun — one match played, no goals, no assists, and an average rating of 7.20 — which makes the training concern more significant than it might appear in isolation. That rating suggests he contributed something in Atalanta's opening win, but without minutes accumulating and combinations developing with Sarri's system, the Belgian risks falling behind the tactical curve before the campaign properly starts.
Sarri's Atalanta sit sixth after one match, with three points from a 2-1 victory. The squad depth question is already live: reports indicate the club are pursuing an additional wide forward, with a target at Bologna proving difficult to prise away. That search, running in parallel with De Ketelaere's fitness uncertainty, tells its own story about where Sarri sees gaps in his attacking options.
The Conference League tie itself — played in Hungary rather than Israel — adds logistical and atmospheric complexity that Sarri described as a tough challenge, warning against complacency. Whether De Ketelaere travels or remains in Bergamo to continue his preparation is a secondary question. The primary one is how quickly he can return to full training and begin translating his potential — assessed at 76 out of 100 by Atalanta's internal metrics — into the kind of consistent output a Sarri side demands from its forwards.
A player rated at 70 overall with room to grow is an asset. A player who cannot train is a problem. Right now, De Ketelaere is both.
