Chelsea midfielder Juan Mata's father and agent will fly to London this week for showdown talks over the Spaniard's future and has not ruled out the possibility of a January return to La Liga with Atletico Madrid, according to The Mirror.
Mata's frustration at reduced first-team opportunities was visible for the first time last week, with the playmaker angry at being withdrawn after 53 minutes of Chelsea's 3-0 win over Southampton.
The 25-year-old has completed just two Premier League games this season, leading to speculation that Paris Saint-Germain, Napoli and Inter Milan are all monitoring his situation closely with a view to a bid this month.
Blues boss Jose Mourinho wants to keep Mata until at least the end of the season, but was forced to admit that he would not stand in the schemer's way if he handed in a transfer request.
Juan senior, the player's dad and representative, wants his son's future clarified and is thought to be due in the capital later this week for a showdown meeting with Blues chiefs.
The subject of that meeting is likely to include rumoured interest from Atletico Madrid, who would be happy to sign Mata on loan in January if he goes public with an intent to seek regular football in the run-up to the World Cup.
