I mean, if we're being honest, that team would absolutely dominate League One.
Dominate??? I doubt it.
That is Moura and Bergwijn's level so maybe they could finally produce unlike they can at the PL level, but based on how they have played for Spurs I wouldn't hold my breath.
Ndombele has shown he doesn't care to work hard against lesser teams so would be fine lazing around out there doing nothing for 85 mins a game, maybe the 5 mins he tried would be enough.
That leaves Son to do all the work and even at League One level the 4 defenders that could focus on him ignoring the other two plugs could likely handle him for the most part.
