Five challenges Pakistan will face ahead of the England series

#4 Mohammad Amir's injury

His potential absence will be a major blow to Pakistan and their chances in the series

The seam-bowling spearhead has been quite successful for Pakistan since his return to international cricket and has been a vital cog to whatever amount success they've had in the last couple of years.

However, Amir walked off with an injury after bowling a few overs in the second innings of the Ireland Test. If the left-arm bowler is unavailable for selection ahead of the first Test at Lords on May 24, it will be a huge blow for the visitors.

Considering it was the same venue where the 26-year-old's career was about to crash into an abrupt finish after the spot-fixing ignominy back in 2010.

He would be rearing to redeem himself on that ground this time around, but it remains to see if his body will recover fast enough for him to set his plans in motion.
