Diego Costa is refusing to attend training at Atletico Madrid.

The former Chelsea striker will not play again this season after being slapped with an eight-game ban for his comments towards the referee during the recent defeat to Barcelona.

And AS reports Costa faces internal action from Atletico for the sending off - which has led to him refusing to take part in training.

Costa was at the club's training ground on Thursday and despite the club confirming he is not injured, he did not take part in the training session.

The Spaniard is contracted until 2023 but he has only managed five goals this season and reports suggest his latest indiscretion could be the final straw for boss Diego Simeone with a move to China mooted.
