Everton boss Roberto Martinez is full of praise for Sam Allardyce's West Ham United.

Everton enjoyed victory over West Ham on Saturday.

"West Ham have been a joy to watch," Martinez said.

"They play dynamic football, really, really attacking-minded. I think the new players they have brought in have brought a lot to the team and into the league.

"And to see them performing straight away, a foreign player coming into this league, is down to the manager.

"What the manager has created is an environment where the team is able to perform from day one so I think West Ham's season has been very, very impressive."
