Zlatan Ibrahimovic can cope with AC Milan's quick turnaround in matches but Rossoneri head coach Stefano Pioli is unsure how long his side will be without fellow key player Hakan Calhanoglu.
Veteran striker Ibrahimovic scored twice in Saturday's 2-1 win over bitter rivals Inter and is part of Milan's 22-man squad for Thursday's Europa League Group H opener with Celtic in Glasgow.
Pioli has resisted the urge to rest his big hitters and insists they can cope with the demands of a packed fixture list, with four more matches to come in the space of 10 days.
