Everton boss Roberto Martinez has branded defensive teams "parasites".

Martinez is fed-up with the defensive tactics of some managers.

"Too many times you see a team that go for being a parasite; they give you the ball, defend, be destructive," Martinez said.

"That system doesn't develop players. It's the opposite - every two years they burn players. They need new players and they need new players to do things players don't enjoy doing.

"I believe the way the game should be played is in a specific manner; taking risks, and getting on the ball and relying on the talent of the players to score goals."
