The midfielder was introduced at half time in place of Santi Cazorla at the Emirates, with the Spaniard having struggled to make an impact on the game up to that point.
It proved to be a wise change from Arsene Wenger as well, as the Frenchman quickly went about helping his side regain a foothold in the game and eventually level the scores through Kieran Gibbs.
And Souness praised Flamini, saying his introduction was the turning point for Arsenal.
“The turning point for Arsenal was bringing Flamini on,” he told Sky Sports.
“All of a sudden he started to put challenges in, whereas before the Tottenham midfield players had bossed the Arsenal midfield. All of a sudden the Tottenham midfielders were looking over their shoulders and not getting the time on the ball.”
Given how poorly Santi Cazorla had performed in the game up until half time, it is fair to say that Flamini changed the game in Arsenal’s favour.
Alongside Francis Coquelin, he gave Arsenal the stable base in midfield that they had been lacking up until that point, allowing them to get back into the game and eventually grab the equaliser.
Given how Cazorla struggled, Arsene Wenger may be tempted to hand the Frenchman a start next time around as his side look to continue their potential Premier League title challenge.
