Top 5 contenders for the 500 Test wickets club

#4 Ravichandran Ashwin (India) - 292 wickets

Ashwin can become the highest wicket-taker ever if he improves his overseas record

Ravichandran Ashwin is on the verge of creating another world record now. He only needs eight wickets in three matches to become the fastest bowler to 300 wickets, breaking the legendary Australian Dennis Lillee's record, who took 56 matches for the same.

Ashwin also holds the Asian record of being the quickest to 200 Test wickets and the world record for being the quickest to 250 wickets. At this rate, he will easily reach the 500+ club in the next few years. Ashwin has a crucial 2018 ahead of him with 12 away tests lined up.

Ashwin has struggled in the overseas conditions generally and would like to prove the world that he isn't just a home track bully.

The prediction is that he will not only reach the 500+ club by 2020 but will also try to beat Muralitharan's world record of 800 wickets. He has good seven to eight years of Test Cricket left in him.
