Michael Vaughan says record-breaking Alastair Cook will be 'a great'

Former England cricket captain Michael Vaughan believes Alastair Cook "will become a great" after the batsman hit his 23rd Test century.

The opener surpassed England's previous record mark of 22 with a century on day two of the third Test against India in Kolkata.

Vaughan says English cricket will be in "safe hands for many years to come" with captain Cook at the helm, and reckons he could get close to the top of the all-time Test runs list - currently headed by India's Sachin Tendulkar on 15,562.
