West Ham United boss Gianfranco Zola says Robert Green is now England's outstanding goalkeeper.

Zola reckons Green's recent improvement is such that he should retain the number one jersey for the World Cup, ahead of the likes of Portsmouth's David James and Birmingham's Joe Hart.

"I think he is good enough to start for England," Zola said.

"It's about what Capello thinks but he has been in very good form.

"He didn't start the season very well but the last few months he has been very good. In my opinion, he has improved because he has learnt from his mistakes.

"I have seen him playing and training and I see him improving. His attitude towards his work is excellent and I'm sure the England staff have seen that too.

"He has always had talent but when things weren't going his way he worked harder to get into the national team and be the number one.

"I thought his body language the other day was excellent. His presence was good.

It is in his hands and I am sure he is focused and determined to keep the position he has now."
