Chelsea striker Diego Costa has revealed how manager Jose Mourinho's experience of title run-ins has filled the whole squad with confidence.
Mourinho's men currently lead the pack at the top of the Premier League, with second-placed Manchester City six points behind the Blues.
Chelsea boss Mourinho has previously won titles with Porto, Inter Milan, Real Madrid and the Blues themselves, and Costa has talked up the impact that the Portuguese has had on his charges.
Costa told The Mirror: "Our manager has won different leagues and knows how to manage a situation like this.
"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."
Costa signed for Chelsea from Atletico Madrid last summer for a fee of around £32m.
