Roma boss is keen to raig one of his former clubs and bring defenders and to Serie A.
Mourinho has already taken a number of players from the Premier League to Roma during his stint in charge of the club, including the likes of England internationals Tammy Abraham and Chris Smalling.
Italian publication Calciomercato report that Chalobah and Sarr are now on his wishlist, with neither man seemingly in first team contention at Chelsea under Mauricio Pochettino.
Chalobah has been struggling with injury and has not played at all this season, while Sarr has not been in any matchday squads either.
The Blues are unlikely to be desperate to keep either player and if appropriate bids come in from Roma in 2024 then they will be allowed to leave.
Roma may well have competition for Chalobah, who was linked with the likes of Bayern Munich, Tottenham Hotspur and Newcastle United over the summer.
The 24-year-old had made an impact at Stamford Bridge over the last two seasons, making 45 Premier League appearances for the club, but he does not look likely to add to that tally.
Sarr has never managed to make a breakthrough into the first team since signing from Nice in 2020.
The Frenchman made eight Premier League appearances in the 2021-22 season, but they have been his only top flight appearances for the club.
Roma have had a mixed season so far under Mourinho, sitting seventh in Serie A with 18 points from 12 games.
The Europa League campaign has produced three wins from four games, but Roma lost their last outing at Slavia Prague.
