The England striker joined the club in a €20 million deadline day deal and is keen to make as big an impact in north London as one of his childhood heroes
The Gunners paid Manchester United €20 million to acquire the England international on transfer deadline day, with Welbeck set to go straight into the first-team following Olivier Giroud’s injury setback.
And the 23-year-old has now aired his determination to prove that Arsene Wenger was right to lure him to London.
“I loved watching Thierry Henry since I was a little kid,” he told Arsenal Player. “My two idols are Ryan Giggs and Thierry Henry so to come to the club where he was and had so much success at is something you can look up to and try to stamp your own print on the club.
“There's definitely competition and I think once you come to a big club, there is always going to be competition.
“Unfortunately there are a couple of injuries at the moment but I think once everyone is fighting fit, everybody will want to be on the pitch scoring goals and that's healthy competition for the squad.”
Welbeck also promised to give the fans “100 per cent in every single game” as the Gunners look to mount a title challenge this season.
“I play with my heart on my sleeve and I'm always going to give my best," he added. "I'll try to give them so many happy days in the coming future.
“I know a lot about Arsenal. I don't think there are many people in England who won't know about Arsenal and what a big club this is.
"The stadium is fantastic and the team has got a legendary manager and magnificent players who have also been brought in.
“It seems like a family club and that's something that's really enticing. I'm so glad to be here.”
