Chelsea striker Diego Costa says the Blues have to bounce back straight away after suffering a heavy defeat against Manchester City on Sunday.
The 3-0 defeat came only days after a disappointing 2-2 draw at home against Swansea City.
And the Spaniard has urged his team-mates to keep a "cool head" ahead of Sunday's tricky away game against West Bromwich Albion.
"I want to do better in order to get back to the national team. I'm working hard for that," Costa is quoted as saying by the Daily Mail.
"We need to improve right now, we need to do things better, but we need to keep a cool head and communicate better.
"The coach did the pre-season just as he needed to, our fitness is fine, we just need to win a game and everything will change.
"I feel very well, I'm coming off an injury but I'm getting minutes and I feel better every time out."
