He's not been featuring for Chelsea since mid/late July, and won't feature in a first team until at least mid/late October (or onwards, as "Dyche fit" is now more than a meme).My understanding is that he will be fit around mid October. I am not sure where you are getting four months from, I haven't seen that anywhere apart from your post.
I'd love to be optimistic but he's a massive donkey and hasn't been as good as that basically-propaganda Tweet makes him out to be. Worst part is he's gonna take minutes from one of our actual own players in Chermiti too. Also hoofball isn't how he likes to play it seems despite being tall.
Hope I'm wrong on all accounts and he's good but this is a proper Everton loan so far - a wasted slot.
