“Azhar also only made a very small alteration but it's amazing the difference it has made in both innings of this last Test. Most of all, he has shown incredible mental toughness at a time when his captaincy has been questioned and his side have been struggling,” Hussain wrote in his column for The Daily Mail.Hussain also believed that a slight technical change with the bat, has been beneficial for Pakistani skipper Azhar Ali, during the ongoing third Test against England in Southampton, as he scored an unbeaten century.Azhar was criticised for his below-par performance by the cricket legends and experts over his failure to grab the opportunity to win the Manchester Test despite being on top and in a better position against the host team.“All too often Azhar got his front leg in the way and was then falling over the crease with his bat coming down at a bad angle.So the bowlers have worked to get his leg across his stumps before producing a nip-backer that gets him plumb lbw,” he said.The adjustment proved beneficial for Azhar as he scored an unbeaten century, 141, in the first innings of the match.“So there comes a time when, if you keep getting out the same way, you have to think, "I've got to make an adjustment here," he said.“Azhar has done that between the last Test and the start of this one and his slight adjustment has been moving his front foot out of the way in his stance, just by a couple of inches, and opening his hips up a bit.”That means he has not been planting his leg in front of off-stump - instead it is in front of middle or middle and leg - and he has looked a lot more confident when England have been targeting those pads,” Hussain said.Maintaining that such a change isn’t an easy task, especially if it has worked well for you in the past, Hussain said: "People will say 'if it is that simple and he can score a century now why didn't he do this before?' but it is not that straightforward."Firstly it doesn't feel natural at first to change something that has served you well everywhere else throughout your career. Also, any change you make can then lead to other forms of dismissal,” he added.
