Former chief selector Dilip Vengsarkar said left-hander Yuvraj Singh lacks the focus to excel at the international level.

"Yuvraj has been given too many opportunities but he has failed to translate his talent into performance on consistent basis in international cricket," Vengsarkar said.

"Yuvi is extremely talented but he lacks focus required to excel in international cricket," he told 'News 24' channel.

Vengsarkar felt the series against England can be a make or break series for Yuvraj.

"Selectors have given Yuvraj three matches to restore his form. In case Yuvraj fails to capitalise on this opportunity, it will be hard for selectors to pick him for the remaining ODIs," said the former India captain.
