Chelsea fullback Marcos Alonso says he wants to be the best in the world.

Chelsea have won the first five matches of the Premier League season and the Spanish full-back has played every minute of those victories, scoring one goal and recording five assists already.

"That's why I came to Chelsea," he told Sky Sports.

"When you come to one of the top teams in the world with some great players, you can fight for that spot and that's what I try to do.

"I want to keep improving and to work hard to be one of the best.

"I want to score more goals, I want to give more assists, I want to do more tackles.

"Everything I can do to help this team is good for the team and good for myself."
