David Luiz's trophy haul speaks for itself.
In his time in England, the centre back has won one Premier League title, two Emirates FA Cups, the Champions League and lifted the Europa League twice.
The Brazil international has been there and done it all - and he believes his experience can help a youthful Arsenal squad.
"I try to give what I have learnt from my life," Luiz said. "I had an opportunity to live here, [had] many fantastic moments in my career and many titles and I just try to make [the squad] understand that everything is possible if you work hard, if you really believe, if you are humble and keep your feet on the ground and take it step by step.
