The Arsenal defender escaped punishment for the challenge in his side's 2-1 loss.
The defender was lucky to avoid a red card in his side’s 2-1 defeat as he went in hard on the Hornets striker early in the game.
Replays showed he had actually jumped in with both feet off the ground and his studs raised in a challenge that should have seen him see a straight red.
Deeney reacted angrily right after the challenge, but he has revealed that the defender was quick to apologise for his challenge.
“I wasn’t happy with that,” he told BT Sport.
“I could have went through him as well and I did my best to keep my studs down but he came over the top.
“Fair play he came and apologised, I was just frustrated initially because they are the ones that can break legs.”
It will now be interesting to see if Gabriel faces retrospective punishment from the FA following the game.
He avoided any sort of punishment from the referee during the match, suggesting that the official had missed the incident during the game.
If that is the case, and it fails to be in his report, then surely the authorities cannot ignore it and will move to ban the defender.
Given Gabriel later apologised it appears he knows what he did and cannot complain should he be the subject of retrospective action.
