Malcom, 21, ticks all the boxes for what Sarri needs in a winger and has more potential than 30-year-old Willian.
Malcom has barely played since signing from Bordeaux this summer.
Will he complete a switch to Camp Nou?
Barca have reportedly made a renewed approach, with Malcom thrown into the deal, which Chelsea are also thought to have refused.
Sources have told ESPN FC it would take a significant cash bid for Chelsea to consider parting with Willian, regarded by Sarri as a key first-team player. "For us, "Willie" is a very important player and it's impossible that he could leave in January".
Chelsea have scored the least goals (36) out of the top six and it's Willian's contribution that's most concerning.
Malcom cost Barca €41million and his slow start has seen a number of transfer and loan links crop up, with Everton originally thought to be front-runners before Marco Silva denied interest.
For one, the Blues would have a direct replacement in attack for the experienced winger, with Malcom possibly being a long-term solution for them.
€60m is a great value for a player like Willian, who is in the final stages of his prime and the current contract at Chelsea.
The Chelsea boss then explained how Willian can further up his displays on the pitch.
Hence, it would have been a transfer coup had Chelsea accepted this offer as it could have helped them financially to pose a Premier League challenge again next season.
