I think the thing to look at with Dougie, is to try and forget his first spell, and ask yourself if he was just a Brazilian midfielder we'd loaned from Juve for the rest of the season, with an option to buy him for £20-ish million in the summer - would we be saying "buy him" based on what we've seen so far?
I think we would. And we know he has another level, too. I don't think he gets in our best 11 when everyone is fit, but that's okay. We need 20 good options, and he provides one.
It will obviously come down to whether Unai thinks he can do more with the money (as we've seen with Elliott), so we'll see - but I certainly wouldn't have any problem with us making his loan permanent in the summer.
