From the little I’ve seen, he does seem a bit better than Bellerin in this regard. We barely attacked against Pool so nobody looked great going forward.
Arteta said he has more quality in attack he didn't say he is more attacking than our other right backs which is what @Monstar-Gunn4r is suggesting.
