Fresh talks have been held over Costa between Chelsea and Atletico, and
there is now a sense that that two clubs are close to agreeing a deal
that is likely to be worth around ￡40m plus significant add-ons.
Atletico are thought to be open to sending Costa on loan for six months,
until he can play for the Spanish club in January, or putting him on a
specialised training regime.
Everton are one of a number of clubs, including Monaco and Marseille,
interested in taking Costa on loan but sources close to the 28-year-old
doubt whether he would want to play in England again up until the New
Year.
Chelsea would not try to block Costa joining Everton on loan, as he would
not have to face them before January and, in theory, he could do damage to
some of their Premier League title rivals.
