Wouldn’t take much adapting to him. But would be concerning that Ruben has had much less success in the same system with, in theory, much wider resources.
Whilst they have a lot of similarities, tactically and in character, Ruben would be a bit of a downgrade on Oli both tactically and with man-management.
It could work out well… but there would be concerns for him to address. If he did get the job, hopefully we would see some growth in the man from what we’ve seen so far. Or if we got more of the Sporting Lisbon man than the Man United man, we’d be okay.
