AC Milan's Ronaldinho has suffered a slight thigh strain and is a doubt for Monday's trip to fourth-placed Napoli.
Massimiliano Allegri, the Milan coach whose side are second in the Serie A table, is planning changes irrespective of the Brazilian's injury following Tuesday's 2-0 loss at Real Madrid in the Champions League.
The game will be the first to be played on a Monday as part of moves to better market Serie A. Other measures include a Sunday lunchtime kick-off, television cameras allowed in the dressing room and half-time interviews.
Juventus forward Alessandro Del Piero will break Giampiero Boniperti's record of 178 Serie A goals for the club if he scores in tomorrow's match at struggling Bologna. Zdenek Grygera, the Juve full-back, is set for a spell on the sidelines after suffering a knee injury.
