Chelsea manager, Antonio Conte, has refused to consider including Diego Costa in first-team training.
The Daily Mail reports Costa will not play for Conte again and has even been barred the player, from practising with his team-mates.
The 28-year-old is also not on the pre-season tour of China and Singapore, having been allowed to extend his summer break, in the hope a transfer deal can be struck.
Atletico Madrid is believed to be the only club keen on the Spain striker, but a deal is complicated, because Diego Simeone’s team are serving a transfer ban until the end of the year.
The two clubs have also been wrangling over the fee and the details of how and when payments would be made.
