Talks between Chelsea and AC Milan are intensifying over Alessio Romagnoli.
And during negotiations on Wednesday, the outline of a deal over Mario Pasalic was settled, reports Sky Italia.
While talks continue over a fee for Romagnoli, Chelsea are willing to send midfielder Pasalic on-loan to Milan for the season.
The deal will be a straight loan, without any permanent option, and could be part of Romagnoli's move to Chelsea.
Chelsea midfielder Pasalic spent last season on-loan with AS Monaco.
