South Coast RoyalOld Man AndrewsNewCorkSeth Could see the majority of clubs in the Premier league sniffing around him. Sheffield United will need a new keeper for one. But he could slot into so many teams across the Premier league. Its probably just Liverpool, City, United and Wolves who have better keepers (unless I'm forgetting someone obvious?)
But yeah, as you say, he has options now.
Chelsea desperately need a new goalkeeper imo, they could do worse than Martinez.
Think Martinez suits the way Arsenal play way more than Leno, Emi is far superior with his feet. Leno is a very good keeper in his own right of course, not suggesting he isn't but I think Martinez has the edge with his distribution. It's not just the fact he can pass very well it's the speed in which he acts. Many times whilst at Reading you'd see him catch a cross and immediately distribute accurately without even thinking about it.
We will see in due course whether Arteta agrees with you and Seth but I suspect Leno will be back in as soon as he is fit.
I reckon Arteta knows his stuff. I'm sure it will be Leno again, as I said he has been one of Arsenals top performers this season, but its certainly not clear cut right now. Arsenal fans are buzzing about Emi on twitter.
