Cellendolo said: "I'm very happy with our defensive performance, I think we've been pretty good for most of the game, and what's a little disappointing is the lack of possession ability, and we made some incredible mistakes when we're in possession.
I think our passes need to be sharper, especially in the opposing half to create a real threat against Chelsea, and that's where we're going to improve over the next few days and then fight for the hope of defeating Tunisia.
I think we have enough scoring opportunities today, but it's also good to save those goals for the next game and get three points, which is also great, and that's more hope for me."
