Emile Heskey believes Leicester are genuine Premier League title contenders and backed them to threaten Liverpool's crown.
The former England international's former clubs meet at Anfield on Sunday in the latest test of the Foxes' credentials.
Leicester have won six straight games in all competitions - having also beaten Manchester City 5-2 in September - after bouncing back from last season's final-day disappointment of missing out on the top four.
Liverpool's title defence has them a point behind the Foxes, top of the Premier League heading into the weekend, and Heskey expects Brendan Rodgers' side to last the course.
