LA Galaxy captain Landon Donovan admits his game has rapidly improved from his spell with Everton.

The 28-year-old revealed his impressions of English football and explained why he will be an even bigger threat to Fabio Capello's side at this summer's World Cup.

"What have I learned? Wow! I've learned a lot," he told the Daily Mail. "The biggest thing from a professional standpoint is to keep yourself going every day. That is so important. The amount these guys put in is so draining, physically, mentally and emotionally. I have so much respect for the Frank Lampards and Steven Gerrards who do it day in, day out. It's the same here at Everton, when you see players like Leighton Baines turning out every week and maintaining standards.

"It's been really great and I can't imagine many players in the world, let alone Americans, can say they have played against and beaten Chelsea and Manchester United in the space of 10 days. That has to be the highlight. It's certainly improved me as a player. I've learned a lot technically and tactically."

This improvement was evident in Everton's 5-1 win over Hull on Sunday when he scored one and set up another.

"My experience puts me in a stronger position for the World Cup," he added. "The biggest plus is I now have the confidence to play against anybody and not fear anyone at all."
