Nigerian forward Ademola Lookman will miss Atalanta’s Champions League showdown against Barcelona on Wednesday due to a knee injury sustained in training, the Serie A club announced Tuesday.

Atalanta revealed that Lookman, 27, injured the lateral joint in his right knee and will not travel to Spain for the match. While the club did not specify a recovery timeline, Italian media suggest he could be sidelined for up to a month.

Lookman’s absence is a significant blow for Atalanta, as he has been pivotal this season with 14 goals and six assists. His hat-trick in last season’s Europa League final against Bayer Leverkusen remains a standout performance.

Atalanta, currently seventh in the Champions League standings, face a must-win scenario against an already-qualified Barcelona to secure direct progression to the last 16. A loss could see them relegated to a play-off spot in the competition.
