It's an interesting topic....
I'm an atco working in an adjacent center to Italy and I coordinate daily with different italian centers. I'm afraid I have to say that their english is not the best, eventhough there are exceptions of course. As long as you keep to standard phraseology it's ok but as soon as you try something outside of that you quickly realize that they didn't understand one single word!!
In my experience it's the same with the french.
Don't mean to offend anyone here but the sad truth is that there are a lot of ATCO:s whose english definitely needs improvement, not only in Italy and France.
I'm not exactly an english-professor myself but I grew up in a country where the films on TV where not dubbed....
