Maresca told Chelsea's website: "Jadon, since we started, is doing well. He was lacking a finish because we had many different games where he arrived one-v-one and he is always looking for an assist. This is good but sometimes he is in a position where he can take a shot and now he is doing better.
"If you look at us this season, from the right winger with Noni and Pedro, the right pocket with Cole, the number nine with Christo and Nico, we have scored goals. From the left side and left pocket, we struggle a little bit but now we start with Enzo and Jadon. With the five attacking players, we need goals and assists from them. All the same.
"Off the ball, the way we work, Pedro and Noni on one side and Jadon and Misha on the other, they have to run when we don’t have the ball. It’s not more than that. You can’t only play football when we have the ball, you have to play it when we don’t have the ball. We require sacrifice and hard work."
