Why would it be a risk to change the starting XI that was in terrible form at the end of the season?
I'd be surprised if Bazunu and Aribo didn't start vs Spurs. Also wouldn't rule out Bella-Kotchap and Lavia either.
Being captain for one half of a friendly because Ward-Prowse and Romeu weren't on the pitch isn't an indication of anything apart from him being a senior player in the squad.
