Chelsea are reportedly keen on a move for Manchester United target Alessio Romagnoli after the Italian's strong start to the season with Serie A giants Milan.
Romagnoli has established himself as Milan boss Gennaro Gattuso's first choice centre back this season, with the Italian choosing to alternate between Mateo Musacchio and Cristian Zapata to partner the 23-year-old at the heart of Milan's defence.
Sarri could be pushed into a move for the Milan
Sarri is also faced with the headache of possibly losing Andreas Christensen, who recently revealed that he's ready to quit the west London club because of a lack of playing time.
The Dane said, as quoted by Sky Sports:
"It's too early to talk about when to change if I'm going to change. But it is clear that it is not a good situation for me."
