'If Harry Kane were to get injured this summer, where would that leave us?'

Emile Heskey feels it is difficult to see where the next main England striker comes from, following the decline of the traditional number nine in recent years.

Bayern Munich forward Harry Kane was the only out-and-out striker named in Thomas Tuchel's 25-man squad for this week's World Cup qualifiers against Serbia and Albania.

While some potential options are missing through either injury or being rested, it has provided a stark reminder of how reliant England remain on 32-year-old Kane.

Former Liverpool and Leicester striker Heskey - who made 62 appearances for England from 1999 until 2010 - feels it always used to be clear who the next leading number nine for the Three Lions would be, but feels that is no longer the case.
