Against Bologna last night, Milan were forced into making two substitutions; Gennaro Gattuso was required to replace Argentine midfielder Lucas Biglia and Turkish midfielder Hakan Çalhanoglu. Both were a result of injury and today, they have estimated their recovery times. This afternoon, Biglia will undergo special instrumental examinations in order to assess the extent of the injury and the consequent recovery techniques to be followed. For Çalhanoglu, on the other hand, he is said to have been replaced principally as a precautionary measure - he will not be subject to examinations and will try to return to proper form in view of the upcoming match against Fiorentina.
