Chelsea boss Luiz Felipe Scolari was delighted with Miroslav Stoch's impact in their late win over Stoke City.
"That was fantastic," he told the club's official website. "Miroslav did very well twice and crossed, we scored and it was good for us.
"It was good for the young players because the young players need an opportunity, but whoever gets the opportunity needs to prove themselves - not only for me, but for the people and the older players.
"Next week maybe the players will believe more in the younger players. There are good rewards and I will always give the young players an opportunity."
