Viera was world class, admittedly he had Emmanuel Petit alongside him who was no slouch!
Yes Petit was also excellent. It's easy to forget though that he had gone before the invincible side.
Also on checking, Bergkamp didn't play anywhere near as much as I thought he had that season. He was perhaps slightly past his best by then. However Henry was at his very considerable peak.
Bergkamp was though one of the first truly top class foreign players (apart from Ardiles) to come to England whilst at his very peak. The others, Ardiles apart, tended to be not quite in the very top level or were maybe past their best. Although Muhren and Thysson at Ipswich were pretty effective.
