Dublin, Aug 23 : The impressive return to action by fast bowlers Jasprit Bumrah and Prasidh Krishna has been the standout performance of India's ongoing T20I series against Ireland. Both Bumrah and Krishna have bowled spells that have enthralled fans and given India the upper edge to take an unassailable 2-0 lead in the three-game series. With the duo set to take part in the upcoming Asia Cup, Sitanshu Kotak, India's head coach on the tour of Ireland, feels both bowlers need more game time to be at their best ahead of the Men's ODI World Cup. 'They were at the National Cricket Academy (NCA) for their RTPs (return to play) and strength. They are very smart; they never looked like they did not get a game, or were out of practice. They looked ready in practice.' 'It is just that these guys need more game time before the World Cup. They will get three games in this series and (also) a few matches in the Asia Cup,' said Kotak ahead of the third T20I. Apart from the duo, young left-handed batter Tilak Varma will also be going for the Asia Cup, though his scores in Ireland have been 0 and 1. Kotak revealed that in the optional practice session, Varma was keen to talk about his processes around mindset and the shots he should play. "He just wanted to practice. He talked about his mindset, and his shot selection and it was a normal discussion on what I think and what his plans are. On tours, if anything, we talk more about tactics. He spoke about how to build his innings and how he should approach the last game." "We do not speak much on technical aspects unless the player requires it and provided there is enough time. I do not think you can change a player technically during a series, within two-three days or a week," he added. With India already winning the series irrespective of the result in the final T20I on Wednesday evening, Kotak said it remains to be seen if players like Jitesh Sharma, Mukesh Kumar, Avesh Khan and Shahbaz Ahmed will get a look into the playing eleven for the final game of the tour. "But if there is a possibility of giving them an opportunity, we will give. It is a short series; the first was a half-game in a way. If we have to give an opportunity to someone, we will have to drop another ' it is difficult to rest someone after giving just one match." "Normally in a five-match series, we try that everybody gets a game or two. We have only three matches here ' half of one game got rained off ' it is difficult to leave out those who are playing," he concluded. /IANS
