Got a very good feeling on Mustafi and Xhaka; I reckon they're going to be up there with the best in their positions over the next few seasons. Think they're both severely underrated signings by both our fans and pundits at the moment.
Holding also looks a big talent. The way he's taken to the Premier League, after taking to the Championship in the manner he did last season, in difficult circumstances, only the good ones do that.
Asano looked really good at the Olympics but the level was dire, so I'll reserve judgement there until I see what he can produce in Germany. But he looks promising and the sort of striker I want us to sign; the antithesis of Giroud and Sanogo. Not that Giroud is a bad player mind, just a striker without any pace is never for me - Asano seems to have it in spades.
Perez, I have no idea about. He looks good in the YouTube videos, and I'm encouraged by a few knowledgeable posters on here rating him, looks a bargain in this market too, but I get the feeling there's at least a reasonable chance he flops here. I'll be shocked if he displaces Giroud any time soon, but well see.
All in all, I'd give the club 8/10 for their summer dealings. I'm a bit disappointed we didn't get in someone special to come in and play as our Number 9, but I accept that's not all on Arsenal because there are very few of them out there and at least they tried with Vardy and actually got in Perez.
Still hope we have something special we're working on before deadline day, but it's good we've done what was needed with time to spare.
