The Brazil-born Spain striker will be available again for Jose Mourinho in Tuesday's Champions League last-16 first-leg at Paris St Germain following a domestic suspension for treading on Liverpool's Emre Can.
Costa was banned retrospectively for the incident during the Capital One Cup semi-final defeat of Liverpool, angering Mourinho, and missed matches with Manchester City, Aston Villa and Everton.
"I've been a target for defenders for a long time, and I am used to getting kicked by them, to get knocked by them," Costa told the Guardian.
"I also fight and tackle, even if some defenders complain at the slightest contact.
"To me, you draw a line under all that as soon as the game is over
We shake hands and it is all [left] on the field.
"I think the referees should think about how many times I am hit or kicked before I get angry about it.
"But referees here in England are good enough and professional, and they also understand well and realise what happens out on the pitch
They take that into account."
Costa has scored 17 times in 19 Premier League appearances for a Chelsea team moulded around the striker.
"Up to now, things have gone phenomenally well for me at Chelsea," Costa added.
"Jose Mourinho has been really clear about what he expects from me, saying he wants me working hard rather than just scoring
Hard work is what he values."
