Despite initial worries over his lack of English, the North Londoners decided Sunday’s FA Cup clash against Middlesbrough was the ideal time to hand the 24-year-old his debut and all went to plan.
Two goals from Olivier Giroud secured a 2-0 victory and Wenger’s side’s passage in to the quarter-finals, and Gabriel came off the pitch unscathed and untroubled after a fairly comfortable afternoon.
When quizzed on Gabriel's performance after the match, Wenger revealed that he was intrigued with how his new signing dealt with the occasion before highlighting three important qualities which were on show.
“It was interesting to observe Gabriel today because he played his first game in a cup game that we absolutely had to win,” Wenger told the club’s official website.
“He has shown three important qualities - great concentration levels, great urgency to defend and good pace, especially on the recovery tackle he made in the box.
“On the other hand, he played a little bit with the handbrake on because he did not want to make a mistake. From what I’ve seen there’s a lot to come from him because technically he is good at passing as well.”
According to renowned statistic website Whoscored.com, the former Vitoria prodigy made two interceptions and eight effective clearances while maintaining a 93.7% pass completion rate.
It was an all-round successful day for Gabriel, but the challenge of proving himself in the Premier League and establishing himself as a first-team player has only just begun.
