Pakistan's assistant coach Aaqib Javed has said bowlers will struggle to produce reverse-swing following the recent rule-change in ODIs mandating the usage of two new balls, one from each end.

"Bowlers will now have to focus on conventional swing," Aaqib said. "I think the overall advantage goes to the new-ball bowlers. In terms of reverse swing, [only] some pitches can alter the condition of the ball so as to aid bowlers at the death. That's when they can take advantage and produce some reverse swing."

After its annual conference in June, the ICC had announced the usage of two balls in one-dayers, and also restricted batting and bowling Powerplays to the period between the 16th and the 40th over.

Aaqib also said the ongoing training camp in Lahore for fast bowlers has helped identify potential talent for the national side.

"There are various bowlers in our domestic circuit, who are taking wickets regularly. We are keeping an eye on their attitude, fitness, discipline and their approach [at the camp]," he said. "Through this method, we have realised that some of them are not fit to play international cricket."
