Manchester City boss Pep Guardiola was extremely impressed with New York City FC star Valentin Castellanos.

The MLS Golden Boot winner impressed for the New York-based team as they won their first MLS Cup, beating Portland Timbers on penalties.

NYC FC is a sister team of Manchester City, and Guardiola spoke about their triumph and Castellanos in particular.

"I think he's a guy who will do the next step in Europe," the City boss said of Castellanos, per the club website.

"What I saw when the scouting department talked to me and (former City assistant and NYCFC boss) Domenec Torrent, when I was there, and Dom was there we talked about him.

"I know he has the quality and I think he is ready to make the step to Europe, we will see where."

He added on the game: "I was really impressed with how they handled extra time.

"When you concede a goal with 10 seconds left to finish the game to be champions in extra time you can be destroyed.

"In extra time, wow, they were much, much better and it means how strong they are these players and the manager.

"And after, the penalties, the goalkeeper (Sean) Johnson made some incredible saves.

"It's a huge compliment for the organisation, for New York City because it's the first time (as MLS champions) and always the first time is special."
