Brighton boss Graham Potter says there is a calmness around the club despite losing key players this summer.
The Seagulls pulled off a 2-1 win over Manchester United at Old Trafford on Sunday.
Albion have lost Yves Bissouma (Tottenham Hotspur) and Marc Cucurella (Chelsea) this summer for a combined £87.5m.
"Losing the players we have does have an impact but inside, the club is quite calm," said Potter.
"You do have to scratch your head because the clubs who bought Yves Bissouma and Marc Cucurella valued them at quite a high price, which suggests they are good players. And you need good players to win matches in the Premier League because it is tough.
"But I always think the collective idea is more important than any individual."
