'Rare to have players like him', India captain Rohit Sharma lauds milestone man R Ashwin | IND vs ENG

No praise is enough for Ravichandran Ashwin, said captain Rohit Sharma on Wednesday, lauding the off-spinner ahead of his 100th Test as a "rare" talent critical for the team's success.

The fifth and final Test against England, starting in Dharamsala on Thursday, is inconsequential to the final outcome of the series as India have already taken an unbeaten 3-1 lead.

But it has become significant due to the 100-Test milestone set to be achieved by Ashwin and England batter Jonny Bairstow.

"(It's a) big achievement for any player to play 100 Tests. It is a big milestone. He has been a match winner for us. What he has done for us, no praise is enough," Rohit said on the eve of the match.

"His performances over the last five-seven years, every series he has contributed. It is rare to have players like him," he added.

"I want to congratulate him for his 100 test landmark, of course to get near it as the toss hasn't happened. It feels good to reap rewards of your hard work," the skipper said.

They have been national teammates for close to decade and half decade but it was more than 20 years back a precocious Mumbai off-spinner Rohit was pitted against a talented opener Ashwin in Vijay Merchant (U-17 back then) and Cooch Behar Trophy (U-19) between 2002-03 to 2005-06.

"As a captain, I have seen him since U-19, U-17 days. He batted at that time, was an opener and then he started bowling. And I used to bowl (off-spin) and then became a batsman, so it became up and down for us but it has been good for Indian cricket."

Ashwin, who for many is a "cricket scientist", has evolved a lot in these 14 years, feels Rohit.

"As a cricketer, he (Ashwin) has evolved in his game and he has a lot of intelligence and if you get a player like this in the team then you don't have to think too much.

"If you give the ball to him, then he drives the game. How to bowl, what field to set and what to do, I am talking about the planning during the game."

The Indian skipper also harped on how process-driven Ashwin is.

"Apart from that what you see on the field is a result of a lot of off field stuff and the work done on one's bowling. I have often seen him bowling with just one stump before a match -- one hour 45 minutes before a game. Bowling at one stump a day before a Test. This is cricket's basics."

"I have seen him regularly bowl at one stump and this has been a process for him. And the biggest thing is that he is a big team player and we saw that in the Rajkot Test when it was a difficult situation for him but he called and said "I want to come back and do something for the team. You see this rarely and when you have players like this then your head is held high."

Ashwin has 507 Test wickets, making him only the second Indian bowler after Anil Kumble (619) to go past the 500-wicket mark.
