Lookman played for just 14 minutes during the team's 2-0 victory over Levante on Saturday.
Before their upcoming Champions League match against Bayern Munich, Simeone urged Lookman to stay patient, work harder, and maintain his confidence, reminding him that challenging periods are a normal part of football.
Simeone emphasized that he has faith in Lookman and doesn't want him to become frustrated due to not being in his best form, as this is a natural part of the game.
The manager encouraged Lookman to focus on his work and believe in his abilities, saying, "This is work, this is believing in what you do."
