But Canaries look set for drop
Onel Hernandez – one of four changes made by Farke after Wednesday’s 4-0 loss at Arsenal – was the hosts’ most threatening player in the first half and he sliced wide after Emiliano Buendia’s pass in the 19th minute.
The first drinks break of the afternoon occurred shortly after and the visitors soon went ahead when play restarted.
Norwich centre-back Timm Klose gave possession away in midfield and Brighton broke at pace with Neal Maupay playing in Mooy down the right, and he produced a fine cross into the area where Trossard stroked home from seven yards.
Seagulls manager Potter would have been delighted with the 25th-minute breakthrough, but opposite number Farke will no doubt have been frustrated at another avoidable goal conceded by his side.
Brighton goalkeeper Mat Ryan was able to comfortably hold Hernandez’s latest effort at the end of the half, after Yves Bissouma took some sting out of the initial shot.
It was almost 2-0 in the 50th minute when Mooy’s free-kick from the left found Dan Burn and he diverted an effort just wide off his back. Norwich responded five minutes later but Buendia’s volley was blocked.
Josip Drmic’s final involvement was a side-footed effort from range that Ryan dealt with easily before the cavalry arrived for the hosts.
Farke brought on Pukki and Cantwell in the 67th minute, with young forward Adam Idah also introduced.
It was the latter who went closest out of the trio, but his deft header from Kenny Mclean’s free-kick in the third minute of stoppage time hit the inside of a post.
Brighton were able to see out the final exchanges and there were big cheers from the visiting bench at full-time with another season of top flight football essentially secured.
