India registered their maiden bilateral series win in South Africa.

Men in Blue also won the 9th ODI series in a row.

South African did not give a tough fight and let Indian team won the ODI series very comfortably.

Now, the South African side have enough time to evaluate the poor performance and fix their drawbacks before World Cup 2019.

Virat Kohli is one of the most dedicated and disciplined athletes in the world.

He is very particular about his exercise and diet so that his performance does not get hampered.

He puts it 100% effort on the field and also pushes the team towards the scope of betterment, he is leading the young and energized talents in the right direction.

His decision making in terms of how to set up the field, how to use the bowlers, squad selection etc is commendable.

He takes criticism very positively and always fights back by producing results.

Number one, number two and number three spots have been set as of now.

Shikhar Dhawan played exceptionally well throughout the series.

Rohit has shown his potential in the previous ODI series against Sri Lanka when he was leading the Indian team temporarily as Virat was absent due to some personal reasons.

Rohit hit a double century and showcased his cricketing calibre in front of the world.

At number three, skipper Kohli is unassailable. He slammed four centuries in the last six ODI games.

Indian team needed a stronghold at number four.

Also, Virat recently shared his concerns over the issue of that he has been experimenting with number four spot.

Ajinkya can be a perfect answer to all the related questions.

Virat just has to groom Ajinkya to play more at number four and inspire the team to greater success.

Virat has recently taken over the responsibility of being captain of Indian cricket team.

Earlier, the captainship was with MS Dhoni.

Dhoni had inspired the team from being an average squad to world's number one team.

He had brought in a lot of transformations in the team. From dedication and discipline on the field to players behaviour off the field.

A successful captain, amazing wicketkeeper, a wise decision maker and magical batsman, Dhoni still plays a very important role in the Indian team.

As he assists Virat in many decisions and even Virat consults him before taking any major decision on the field which shows how important Doni's role is going to be in the upcoming World Cup.

Hardik Pandya is being groomed not to be an all-rounder but to be a specialist.

In the last two games, due to Kedar's absence, Pandya completed his 10-overs spell with a decent economy rate.

Virat is polishing him as the fifth bowler and also letting him bat at number five or six to build up a strong middle batting order.

In the first ODI against South Africa, India decided to play three seamers, and three spinners.

Kohli was banking on his spinners and they produced the results too.

Kuldeep Yadav took three crucial wickets of David Miller, JP Duminy and Chris Morris and Chahal got 2 - of Markram and Quinton de Kock. The duo excelled in their first proper overseas outing, underlining the team management's faith in leg spin since July last year.

Recently, Virat had emphasised that spinners give results on any pitch, abroad as well as on home soil.

And that's exactly what happened.

Bhuveneshwar Kumar has been magnificent in Test matches and as well as in limited overs format.

Jasprit Bumrah is the ultimate solution when it comes to death overs bowling with his variety of spells, from deadly yorkers to inline full-length deliveries.

Hardik Pandya obviously giving extra support to the main bowlers.

Shardul Thakur played well in the 6th ODI against South Africa when he took 4 crucial wickets.

Also, Axar Patel and Mohammed Shami who are currently in form and are sitting on the bench.

There is a very strong competition to get in the playing XI.

Every individual is working hard to affix their places in the team.

This might be the reason why team India has emerged as world number one team because from the staff members to the players, everybody is giving their 100%.

Indian team is blessed with lots of youngsters, thanks to Indian Premier League and competitive Ranji matches.

IPL has given many newcomers like Jasprit Bumrah, Hardik Pandya etc.

Recently, the Under-19 team won the World Cup and they are also set ready to claim their places in the senior team.

Players like Prithvi Shaw, Manjot Kalra, Shubman Gill were exceptionally well as their performance was mesmerizing.
