Thanks for these, yeah, I think it depends on what these sites use to calculate xG.
This site has Arsenal above Spurs for xG for instance.

Anyway, I don't think it's a big surprise Spurs had a higher xG, they have a couple of world class players at the top end of the pitch that helps with that.
We know we need to improve chance creation and finishing, it's why we are targeting players at the top end of the pitch to help with that. Not sure the players Spurs are targeting move the needle that much for them in terms of that, but they should certainly make them a more solid and rounded team.
