The bench beckons for both Brazilians given Ronaldinho's alarming dip in form for Milan and Roma coach Claudio Ranieri's refusal to consider Adriano from the start for big games.
The stepovers, dropped shoulders, ever-present grin and mesmeric skill which once delighted Barcelona supporters are a distant memory for Ronaldinho, just like his compatriot's barnstorming runs and immense strength shown at Parma and Inter Milan.
The duo's inability to break into their sides have led to media reports in Brazil that both may move home in January with Palmeiras chasing Ronaldinho and Corinthians interested in Adriano, who only joined Roma in the close season.
Ronaldinho's Milan deal is up in June and so far there have been no clear signals that the club will offer him a renewal, although coach Massimiliano Allegri dismissed suggestions he would offload the player before the end of the season.
"Ronaldinho can be useful to the team and is staying until June at least," he told reporters.
His current front three of Zlatan Ibrahimovic, Robinho and Kevin Prince Boateng, all new signings, have scored a goal each in their last two league wins so rotation looks unlikely as a three-week winter break begins after this weekend's matches.
Last term's runners-up Roma are sixth, 10 points behind Milan, but with the ability to cause in-form Rossoneri goalkeeper Christian Abbiati real problems with former Milan frontman Marco Borriello especially keen to do well.
Second-placed Juventus are six adrift of Milan and travel to Chievo on Sunday buoyed by last weekend's last-gasp win over rivals Lazio, who entertain Udinese.
