Jimmy Anderson is one of Test cricket's all time greats.

There is no doubt about that.

The 40-year-old has 689 Test wickets over a career that has spanned two decades.

Yet against Australia, he has struggled.

His overall Test average is an incredible 26.31.

Against Australia that blows out to 35.38 - comfortably his highest against any country in Test cricket.

What surprised me was that his average in Australia is not necessarily the issue, but against Australia in England.

In Australia, Anderson averages 34.01 and has 68 wickets in 21 Tests.

In England against Australia he has taken 48 wickets in 18 Tests at an average of 37.33...
