With agents running the game, Wenger would've had information a long time ago. He kept talking about 'deadline day poker'. You can call him lucky this year, you can say he was lucky last year but the deadline deals did get done. With Man Utd looking likely to get Falcao, Wenger did say he wasn't surprised that Welbeck was available. Tottenham were heavily linked with him too before deadline day. He said the surprise was about the 'loan v permanent' situation. As invisible says the 'luck' involved was probably Giroud getting injured because Wenger might've gambled on Giroud's usually reliable fitness levels.
I'd say he's taking a big chance on the CB situation but overall the squad was strengthened. I'd say 3 decent signings, 1 potentially great signing (Chambers) and 1 brilliant signing (Sanchez). I expected worse at the start of the window.
