Despite disciplinary issues in the past, the former Spurs defender says it is important for the midfielder to keep his "edge"
Former Tottenham captain Ledley King believes it is important Dele Alli keeps his "edge", even if other teams target the England international.
Alli has enjoyed a meteoric rise since making his Spurs debut in August 2015, scoring 23 goals in all competitions and becoming an regular under Mauricio Pochettino.
However, he has also encountered a number of disciplinary problems with 15 bookings across his 80 appearances, while he also served a three-match ban for punching West Brom's Claudio Yacob last season.
