Chelsea fullback Wallace is pushing manager Jose Mourinho to make a decision over his future.
Wallace wants to move to Benfica next season and hopes for a decision to be made before preseason kicks off.
Record says Chelsea have already opened talks with Benfica about placing Wallace on-loan in Lisbon. The English champs have insisted Wallace is not for sale.
Chelsea are also demanding Benfica cover Wallace's entire salary for the deal to go-ahead.
Blues partners Vitesse Arnhem and Excelsior Mouscron are also interested in the young Brazilian.
