Christian Pulisic is loving life with Chelsea.

The USA international, 20, has featured in all four of Chelsea's Premier League games this season after joining from Borussia Dortmund in the summer.

"It's everything I hoped it would be and more," Pulisic told reporters Wednesday ahead of the USA's clash with Mexico.

"The speed, it's very intense. The games are very intense. Every single game I've played so far has had a new challenge.

"They've helped me so much over there getting accustomed to everything, and it's been great learning under Frank.

"I'm still learning a lot and have a long way to go, but it's been great so far."
