About Zaza, I'm not a big fan of his and his pricetag, but it seems a done deal anyways.
And remember all the strikers we've brought in january pretty much every year? Zaza will be fullfilling exactly that role for years to come. And better, as he doesn't need any time to settle in the strikers brought in newly every year require. Moreoever, he's still young, and there's always the possibility of him developing into something much better - he'll probably never be worldclass, but weirder transformations have happened.
