Chelsea manager Guus Hiddink believes that Diego Costa will have to get used to playing against physical defenders.

The Spain international was again involved in a couple of scuffles in the goalless draw with Watford and received a yellow card for his scrap against Hornets defender Juan Carlos Paredes in the first half.

"This league is physical, when you see our central defenders and our opponents' central defenders," Hiddink said after the game.

"He [Costa] likes to go physical but he must do within the rules.

"Sometimes players get physical and he has to get used to that."
