England relish 'fear factor' of returning paceman Jofra Archer

England are eager to unleash Jofra Archer's 'fear factor' against Pakistan as the paceman prepares to return from a long injury lay-off ahead of next month's T20 World Cup, says team-mate Sam Curran. Injuries have blighted Archer's international career and he has not played top-level cricket for 14 months due to back and elbow issues.
