Newcastle had a decent shout for a penalty against Arsenal when Callum Wilson was nudged by Nuno Tavares.
It was a subjective call by referee Stuart Attwell, who decided there was not enough contact to award a spot-kick.
Toon boss Eddie Howe appealed and Tavares gave Attwell a decision to make.
Arsenal were fortunate because had Attwell awarded a penalty there would have also been a call on whether Tavares denied a goal scoring opportunity.
Luckily for the Gunners, VAR official Darren England did not think it was a clear and obvious error.
On the other side, Newcastle defender Jamaal Lascelles was lucky to get away with a reckless challenge on Gabriel Martinelli. The Magpies ace barged into Martinelli with the use of his shoulder.
On another day, both of these incidents could easily have resulted in penalties.
