T20 World Cup: England formidable even without Tymal Mills, Jason Roy, says New Zealand captain Kane Williamson

New Zealand captain Kane Williamson believes England will be a formidable opponent even without Tymal Mills and Jason Roy in Wednesday's semi-final of the T20 World Cup in Abu Dhabi.

Title favourites but injury hit England will bank on their X-Factor players to upstage a remarkably consistent New Zealand in the first semifinal of the T20 World Cup in Abu Dhabi on Wednesday.

Paceman Mills has been ruled out of the tournament with a thigh strain, while opener Roy has been thrown out of action by a calf injury in two late blows to 2010 champions England.
