Pakistan batsman Younis Khan believes India's recent hammering of South Africa was not a good advert for Test cricket owing to the assistance the pitches gave to spinners.
The Proteas had not lost a Test series overseas for nine years until they were thrashed 3-0 in the recent four-match series.
Spinners Ravichandran Ashwin and Ravindra Jadeja took 31 and 23 wickets respectively as South Africa failed to cope with excessive turn.
The International Cricket Council (ICC) handed an official warning to the Jamtha Stadium in Nagpur for the quality of a pitch for the third Test which was rated as "poor" following a review.
And Younis was not impressed with what he saw of such a one-sided series.
He told PTI: "I don't think it was good advertisement for Test cricket in the recent India and South Africa series that the ball was turning from the first day onwards. The element of competition disappears on such pitches.
"The pitches nowadays in these countries also are not the same as they were a decade or two ago. Look at Australia, you don't see the same pace or bounce. Similarly in England not all pitches now have lot of seam movement."
Younis also expressed his concern over the influence of Twenty20 cricket.
He added: "T20 cricket has been a big step forward for cricket but unfortunately it has been allowed unsupervised growth and that has had negative effects on the players many of whom now just think that just play T20 leagues and earn well.
"Nowadays there are T20 leagues being played everywhere but the quality and big money is there only in IPL or perhaps the Big Bash. With so many leagues round the year, players are only focusing on this format and it is not good for Test or ODI cricket.
"There has been a decline in the growth of quality players because of this scenario."
