Chelsea midfielder Frank Lampard insists England won't underestimate World Cup qualifying opponents Montenegro.

Montenegro maintained their two-point advantage over England with a 1-0 win in Moldova on Friday night.

Lampard said: "Some of their players are playing at the top level in European football. We have been there before, so we know the dangers.

"You look at the state of the group and it's a really critical game. We have to be ready for it."
