Chelsea boss Mauricio Pochettino has told his players "potential" isn't enough.

Pochettino was speaking ahead of tonight's clash with Manchester United.

He said: "Football is about talent, about players with [a mix of] talent and the right mentality. Mentality means you have the capacity to deal with the pressure and express your talent without limitation.

“It's about translating the same feelings you had as a child to when you play for Chelsea, with 50,000 people there and the cameras, for relegation or to win the title.

“That is the capacity you have to identify in a player. You have to have this (head) and this (heart)."

He added: “We have to understand - what does it mean, potential?

“'I have potential' - what does it mean? Potential what? We need to assess the players we have today and we can help them evolve but to what level?

“Potential teams, potential players, potential coaches. Potential, potential, potential. But we need to win today, no? Now I am teaching you."
