Diego Costa: Why I threw my bib at Jose Mourinho

The Chelsea striker has failed to make an impact this season and has scored just four goals in 19 appearances.And an ongoing rift with Jose Mourinho has increased speculation of Costa heading for the exit at Stamford Bridge.



However, the 27-year-old claims his relationship with the Special One is fine.
"Our relationship is exciting, we got along very well. There are things I have to control, but it [throwing the bib] was an impulse," the Spaniard told FourFourTwo.
"I have to improve. The start of the season hasn't been good for me, either in play or in goals. I know I have to improve so that [Vincent] Del Bosque calls me up for the Euros. I have to work and fight."
Despite the Blues progressing to the last 16 of the Champions League last night, the under-fire striker admitted a return to La Liga is a possibility.
I don't know if I'll go back to Atletico. Life always takes plenty of twists and turns. Look where Filipe Luis is," he added.
The truth is that I want the best for Atletico, I always cheer them on from afar.
It would be better not to meet Atletico now, they're a very uncomfortable team to play. I want the best for them. If I could choose, I want to face them in the Champions League final
