After Arsenal's stunning Champions League quarterfinal win over Real Madrid, Walcott told BBC Sport: 'Mikel Arteta has built this Arsenal team from his mind and his connections with each individual talent in that team, and he's built them to be one mind.'
'When I say one mind, I mean he's so serious and some people say he's too serious, but everyone's on the same path as him. And that's why I think their aura is him.'
'That's the difference about Arsenal, they don't have the players with the big egos. They're a team and I think Arteta takes it away from the team. I think it's a good thing.'
Walcott also had a word for Bukayo Saka, who shone despite having a 13th minute penalty saved by Real goalkeeper Thibaut Courtois.
'He typified it from start to finish because he had a night where it could've gone the other way for him but, for me, he is such a resilient character in that dressing room.'
