Alan Shearer has explained why Unai Emery’s substitutes were very effective during Arsenal’s derby victory against Tottenham Hotspur.

Speaking on BBC’s Match of the Day programme on Sunday, Shearer was full of praise for how Emery used his options off the bench with two of those substitutes coming in on the stroke of half-time.

Pierre-Emerick Aubameyang opened the scoring for Arsenal with penalty kick only for Tottenham to turn things around courtesy of goals from Eric Dier and Harry Kane.

It was through the hard work of Emery’s substitutes that the Gunners regained control of the match, firstly through another Aubameyang goal that levelled the score at 2-2, before Lacazette and Lucas Torreira finished off the visitors.

Shearer hailed Emery’s decision to take off Alex Iwobi and Henrikh Mkhitaryan as the key reason why the Gunners saw off their North London rivals.

“He did it brilliantly today,” he said, according to Football.London.

“At half-time, Iwobi and Mkhitaryan were ineffective in the first half.”

“He brought Ramsey and Lacazette on and what these two players did was make the pitch bigger, stretched Tottenham out and played Ramsey in the No. 10 role.”

“They invited him to run in behind, get in between the centre-halves Juan Foyth and Jan Vertonghen, and he did that all the second half.”
