Upgrading to Laravel 5.0 from Laravel 4.2

I've just updated to Laravel 5.0. I have a big project and It's almost impossible to use "use App\Model" in the top of every controller. How can I add the models in the global namespace? I want it to be as It was in Laravel 4.2, so I would not have to make use of those models everytime I'd use them...
