Gallagher praised Jones for not succumbing to pressure and for thoroughly reviewing the footage before making a measured decision.
"It's all about has he grabbed him at the top of the shirt or by the throat? The referee has looked and looked. Rob Jones hasn't knee-jerked and given him a red card. He's studied it," he added.
Whereas, another ex-official, Keith Hackett, argued that Cucurella was lucky to stay on the pitch.
"Cucurella is beginning to become a serious offender in games, and match officials in their preparations should be aware that he is a player to keep an eye on," he told Football Insider.
"His act is a blatant unfair impeding offence for which he should have received a yellow card."
