The former Manchester City came off the bench to score twice.
Post-match, he revealed that the secret to his fast start as a Gunner was the welcome he had received this week, and his excitement of being at his new club.
“I’m so, so proud. I’m proud to be here at this big club,” he said.
“I’ve completed four or five days together with the lads, and I just want to say thank you to everyone at Arsenal because they make me feel at home. Everyone is talking, coming to me and saying ‘good luck, we are happy to have you here’, and I’m happy to be here as well. That makes me feel at home.”
He believes there is much more to come once he gains match sharpness and becomes used to playing with his new teammates, whom he was impressed with for their desire to overturn a two-goal deficit.
“I’m feeling good,” he said about his fitness levels. “Sometimes it’s hard because I had more than 20 days without running, without doing anything, just trying to get some sleep with my new baby and my girlfriend!
“Today was a difficult first half. We have to understand a little bit because we had young players, and they are a strong team. They played long ball, so it was difficult for us. But at the end we came back, and because everyone is together like a team, we did it.”
Looking ahead to the rest of pre-season, Gabriel added: “I’ve just come to be part of this amazing club, amazing team, and then to win together.
“I believe a lot in the project at this club. I can’t wait to play, at our amazing stadium.”
This is the baddest guy around town. Hook me up so that we can share some routine infor in the area.
