Exactly, there were a fair few who didn't want us to sign Sanchez last summer because they felt the money could be better spent elsewhere and because most of us anticipated Podolski, Chamberlain, Walcott, Ozil, Ramsey and Wilshere playing a bigger role this season. And that made sense - at the time.
It's quite hard to plan exactly how a season goes and any sensible signing like Cech should be welcomed with open arms. So what if he fails? If we're so keen on replicating the likes of Manchester City, United and Chelsea we need to be less loyal to our players and take more chances. People give United grief for Falcao but, in truth, it was a gamble worth taking and it was a smart move. And now that we have some decent squad depth, I'm in favour of just signing top players in whatever position we can sign them because even a DM and a solid RB changed our fortunes dramatically this season.
At the very least it sends a message to the squad that the expectations of this club are higher that they used to be. The signings of Ozil and Sanchez did that, I'm sure signing Cech will send the same message.
