Former Pakistan all-rounder Azhar Mahmood said that Yasir Shah can cause serious problems for England when they visit the UAE in October.
The English side are set to face the Green-shirts in three Tests, four ODIs and three Twenty20s in a series starting from October 13.
England side who have beaten Australia recently to regain the Ashes will be in deep water against Yasir on UAE soil, he said.
“Yasir will be the key for Pakistan,” wrote Azhar in his blog for PakPassion.
England are not the best playing spin especially leg-spin and he thing young-leggi will have a major say in the outcome of the Test series, he added.
