Manchester City and England defender Kyle Walker has named former Liverpool ace Sadio Mane as the toughest opponent he has faced during his career.
Walker is currently in Qatar as part of England's 26-man squad for the World Cup finals and has faced a surplus of questions about his defending ability as he bids to thwart France superstar Kylian Mbappe during Saturday's quarter-final meeting.
The two nations will go head-to-head in Doha in two days' time for a place in the semi-final, with the winner facing either Morocco or Portugal next week.
