Diego Costa has revealed Jose Mourinho has urged the Chelsea squad to stay "calm" and focus in order to beat Manchester City and Arsenal for the Premier League title.

The Blues host Stoke City on Saturday 4 April, still holding the top of the Premier League table, six points above Manuel Pellegrini's side and seven away from the Gunners with one game in hand.

After having won just two of their last seven games at Stamford Bridge and following the Champions League disappointed elimination against Paris Saint Germain, there have been some concerns over whether the West London side will manage to keep the leadership until the end of the campaign.

The Premier League holders are expected to push in the eight games remaining following their Champions League knockout while Mourinho himself recently claimed Arsenal have also joined the battle for the title.

But Costa is confident that the boss will see the Blues into securing the double, following their win over Tottenham in the Capital One Cup earlier last month.

"Our manager has won different leagues and knows how to manage a situation like this," Costa said, according to Standard Sport.

"Like the great manager he is, he has told us what we need to do now, which is just to stay calm.

"He's right because everything depends on us now. We know that the Premier League is complicated. It's not easy so we know we have to improve. We all need to dig in and give something extra because we have this title in our hands and we can't let it slip away."

The Spanish international has also expressed his delight over his summer move to the Premier League as he is enjoying his time at West London despite the questions about his special temper.

"I have been receiving that kind of treatment for a long time, so I will try to improve and not fall into the trap. But sometimes I do try to wind them up.

"Everyone wants to win and do their best for their club. In my own way, I try to give my all for my team and fans — my opponent will do the same so I don't complain because it's part of the game.

"I will keep fighting and try to give my best for the team. Things are going well for me. I can't deny I'm competitive, I'm a fighter. That's how the League is here."

Meanwhile it is still uncertain whether the striker will be available for selection on Saturday after he sustained a hamstring injury during the victory over Hull City just before the international break, forcing him to withdraw from the Spain squad.
