Antonio Conte believes Chelsea have the psychological staying power to win the Premier League after restoring their seven-point lead at the top of the table on Tuesday night.
Diego Costa ended his seven-game goal drought with a brace against Southampton to ensure the Blues took a major step towards the league title.
And Conte said: 'I think that we passed a big, big step. A big psychological step after the defeat against Manchester United. Because, against United, we lost three points and then you had to prepare a semi-final against Tottenham. And then another tough game in the league.
