Arsenal scored two goals in the last seven minutes on Saturday to ensure they left Goodison Park with a point.
Everton had gone 2-0 ahead courtesy of Seamus Coleman and Steven Naismith but late strikes from Aaron Ramsey and substitute Olivier Giroud ensured the honours were shared as the Toffees failed to replicate their fine victory in the corresponding fixture last season.
While the goal-scorers stole the headlines, one young Arsenal defender continued his excellent start to life under Arsene Wenger.
The Everton man is 13 years Chambers' senior, but despite his tender years the Arsenal player made more effective headed clearances, won more aerial duels and had a far better passing accuracy than the Toffees star.
He also matched Jagielka stride for stride when it came to both tackles won (two each) and effective clearances (10 apiece).
Chambers' outstanding passing accuracy of 96% put Jagielka's 83% in the shade, and if he continues like this the Arsenal player could be Wenger's first-choice centre-back sooner rather than later...if he isn't already.
