You really dont understand cricket at all.
Can you even define a rank turner?
YK has scored masses of runs playing against spin in the second innings. The UAE is where spinners have taken as much wickets as spinners take in India or anywhere else.
YK is one of the greatest players of spin of all time. Root and Williamson will never get close to his skills against spin but can match them on pace bowling pitches.
I am afraid you are the only who needs a bit of education.
Yes I can define a rank turner. It is a pitch where you get sharp turn from day 1, and if you want to see what a rank turner looks like, look no further than the pitches India have served to Australia, South Africa and New Zealand in the last 3 years and the pitches Bangladesh served to England in this series.
They have more turn on day 1 than a UAE pitch on day 5. UAE pitches are proper highways for the first 3 days and the turn in the last two days is nothing like what you see on proper rank turners.
No one will disputes that Younis is a brilliant player of spin, but he hasn't been tested on a proper rank turner in years.
The fact that you are counting the total number of wickets by spinners in the UAE and are using that to prove that the pitches are equally spin friendly as the Indian and Bangladeshi ones exposes your misunderstanding.
Just look at the average scores in India and Bangladesh lately and compare it to the average scores in the UAE, and also compare individual batting averages.
Pakistan might be brilliant against spin, but look at the output of Williamson in UAE and then compare his output in India.
Cook managed a 260 in Abu Dhabi but he failed to score a hundred in Bangladesh.
Root was much better against Pakistan in the UAE than he was against Bangladesh in Bangladesh.
Ross Taylor, a mediocre player of spin, failed in India badly but scored a hundred in the UAE.
Amla and de Villiers scored hundreds in the UAE in 2013 but couldn't do it in India last year.
It is matter of fact not conjecture; Pakistani batsmen have not been tested on proper rank turners ever since they have started playing in the UAE, and if they tour India or Bangladesh now they will probably not get such rank turners anyway because the opposition will also account for the threat of Yasir, but these teams produce rank turners for teams like Australia, South Africa, England and New Zealand because they lack a top quality spinner.
