It's been a rocky road for Christian Pulisic since he linked up with the squad this summer following his big money move from Borussia Dortmund to Chelsea. 

Featuring in the first four games and starting three of those, it looked liked the perfect move for the 21-year-old, but the honeymoon period ended and in September, Pulisic's patience, determination and resolve was tested the limit. 

He was benched for all of the Blues' fixtures in the Premier League in September against Wolves, Liverpool and Brighton, and cries for Pulisic to get some game time under Frank Lampard were getting louder and louder for every minute that passed by.

But things have been on the up for Christian Pulisic. He waited his turn after the upturn in form of Willian and the returning Callum Hudson-Odoi, and since being given his chance in the side once again, the 21-year-old has excelled. 

A hat-trick against Burnley, his first three goals for Chelsea, and an assist in the vital Champions League victory in midweek against Ajax has made Christian Pulisic a real case to be starting for Chelsea in the coming weeks. 

His hat-trick and recent performances have not only impressed the fans, his teammates, but most importantly - head coach Frank Lampard. 

Pulisic revealed that Frank Lampard told him how much he believes in him, and now the USA international is looking to continue to work hard in order to prove his worth in West London.

"He believes in me and he's told me that. You have to keep working hard in training and earn your spot, that's how it is at the highest level. I'm going to continue to do so. This is hopefully just the start. I didn't come here expecting everything to be easy and have an easy route and start every game."

Christian Pulisic is the star, the poster boy of football in the United States, but he doesn't feel any pressure on his back after his big move to London and revealed his relief at netting his first few goals for the club. 

"I don't feel pressure from back home at all. I know who I need to worry about at home and that is my family and my closest friends and those who care about me. And I have their support and that is what matters to me.

"Of course there is a sense of relief — you could see that in my emotions after the first goal. That relief of getting my first goal and being able to help my team at this level. It's really good for me."
