Brian told arsenal.com: "Having my brother Arthur alongside me at Arsenal has been great. Knowing that I can turn to him for anything I need is brilliant. He's faced numerous challenges and has always risen to the occasion, constantly striving to improve.
"I couldn't be prouder of his recent accomplishments. In the past couple of years he's won the Austrian Cup with Sturm Graz in 2023, and just this season he achieved promotion with Wrexham and was in WhoScored's League Two team of the season. Seeing his success motivates me to push myself even further and achieve similar milestones in my own career.
"Playing alongside Jurrien Timber in the Blackburn and Liverpool U21 games was brilliant. His leadership on the pitch and his exceptional play highlighted the step up from under-21 level to the first team. His ability to keep possession, communicate effectively and his overall performance showcased the standard required at the highest level.
'It was a valuable experience to share the pitch with him, as it provided us with a clear perspective on the levels we must strive to reach to break into the first team."
