Atletico Madrid aim to low ball Chelsea over a deal for Diego Costa.

After defeat in the FA Cup final on Saturday, Costa declared he was willing to return to Atletico should Chelsea choose to sell.

Atletico coach Diego Simeone is keen on a reunion, but club chiefs will drive a hard bargain.

The Independent says Atletico won't go higher than £20 million for Costa - leaving Chelsea with a dilemma.

The Blues rejected a £75 million offer from Tianjin in January for the striker, who now has no interest in playing in China.

As a result, if Chelsea wish to move him on, they're left having to negotiate a fee with Atletico - which know they hold all the cards.
