The castigation followed Smith overseeing ball tampering in a Test match against South Africa which resulted in him and fellow batsman David Warner and Cameron Bancroft being suspended from international cricket.

Having returned to the Test team for the successful Ashes series we can only describe Smith's on-field performance now as imperious, near unsurpassed and dazzling.

The Sydneysider has totted up 671 runs at an average of 134.2 in three Tests this northern summer.

He has appeared as though he is toying with English bowlers at times and on a different plane to his team-mates.

Considering the amount of pressure Smith found himself under after the South African episode and the wilderness he has returned from it is a remarkable effort.

Even more so when contrasted against the experience of his former vice-captain Warner.

The usually pugnacious opener has had three consecutive ducks and is averaging 9.80, a number lower than the 12 being averaged by England's No.11 Jack Leach.

Smith's sublime series, which has culminated in Australia retaining the urn, is testament to his dedication which sees him do extra training and shadow bat in his hotel room as he barely sleeps during Test matches.

It also demonstrates a strong will with Smith's arrival at the crease throughout the Ashes accompanied by a round of boos from English supporters.

The former captain has shown an ability to shut out the hostility, something that may have worn down a less determined soul.

Smith's deeds have prompted speculation that he should return to the captaincy and replace wicketkeeper Tim Paine who has filled the role since the infamous Test in Cape Town.

That is understandable, but there is an argument to say Smith is playing so well because he doe not have the burden of having to think intricately about overall strategy and off-field duties such as media commitments.

He is enjoying a uncomplicated time thanks to his superior skills and so are we as evidenced in victory at Old Trafford in the fourth Test.
