Is Diego Costa some kind of cyborg that thrives on yellow cards?
The controversial Chelsea front man can't seem to get through 90 minutes without getting involved in some bit of trouble.
Costa returned to the Blues starting XI for their home tie with Porto and it took him just 20 minutes to draw the referee's attention.
The striker was chasing a ball into the Porto box but was beaten to it by international teammate Iker Casillas in the first half of Wednesday night's Champions League tie.
Not happy to lose out in anything, Costa left a leg behind which did come into contact with Casillas but, to be fair to Costa, the goalkeeper went to ground very easily.
Still... never a dull moment.
