The England cricket team batting coach Graham Gooch says captain Alastair Cook has the potential to match Sachin Tendulkar's run-scoring feats.
The 27-year-old Cook became the youngest player to reach 7,000 Test runs and England's most prolific centurion with his 23rd as England beat India in the third test in Kolkata.
39-year-old Tendulkar has a record 15,643 Test runs and 51 hundreds.
Gooch says Cook can pass Ricky Ponting and Tendulkar to become the top batsman in the world.
England only need a draw in the fourth and final test against India, which is underway in Nagpur, to win the series.
