Karachi: Worcestershire's bowling coach Matt Mason has issued a warning to batsman all over the world, saying Saeed Ajmal has returned to his original best and would pose a great threat to all batsmen when he plays for Pakistan.

Ajmal, who is making a comeback to competitive cricket with a re-moulded action, returned with impressive figures of 8/100 in Worcestershire's innings defeat of Hampshire, picking up his first five-wicket haul since February.
