Chelsea have set their asking price for Diego Costa.
The Times says they want more than £60m for the striker.
The striker was expected to join Chinese Super League outfit Tianjin Quanjian in a £76m deal this summer.
However, that deal is reportedly in doubt after the Chinese Football Association announced a new “100 per cent tax" on foreign player spending.
Chelsea have decided to sell Costa only if they receive an offer in excess of £60m.
And given that Tianjin have potentially been priced out of a move, they suggest a return to Atletico Madrid could be on the cards.
