Trailing 2-0 at the break to the Premier League leaders, Ansu Fati pulled one back but City held on for a 2-1 win at the Etihad.
Reflecting on the game, Albionâs German midfielder admitted the second-half display was a big improvement.
âIn the first half we lost a lot of possession and couldnât press them like we know we can,â he said. âYou have to get it in your head that if you donât keep the ball well enough you are going to suffer.
âItâs hard to regain it against City and we conceded two goals again. We concede too many, we know that. Weâre working hard to keep clean sheets because we know we have to do that to be successful.
âThe second half was the opposite and you saw the real Brighton. The manager said we needed to be braver and show our style and in the second half we did that. We put more pressure on them and after we got it to 2-1 we had moments to score the equaliser.
âSo there are positives for us. We have Ajax on Thursday [in the Europa League] and Fulham in the league after that and they are really big games for us at the Amex.â
As well as dropping points, Albion also lost Danny Welbeck and Solly Match to injuries. âThat made it a difficult day for us, losing Solly and Danny who are important players was not great," added Gross.
