Lookman has been in impressive form in the Champions League this season, scoring four goals and providing two assists in six appearances, including a goal in Atalanta's 5-0 win over Sturm Graz last week.
Atalanta will face a tough test against Barcelona at the Nou Camp on Wednesday and will have to do without Lookman's services.
