Chelsea are pushing to close the signing of Sporting CP midfielder Manuel Ugarte this week.
Chelsea hope to wrap up the deal in the coming hours, so making new manager Mauricio Pochettino's first signing of his rein.
Ugarte's deal carries a 60m buyout clause, so easing any concerns over negotiations.
Record says Chelsea are now in the final stages of agreeing personal terms with Ugarte's camp despite competition from PSG.
There is a confidence Ugarte will sign for the Blues in the early part of the coming week.
