Graham Potter was left frustrated after a brilliant performance from Aston Villa's Emi Martinez denied Albion victory at the Amex.
The Villa keeper made four world-class saves in the goalless draw which stretched Albion's unbeaten Premier League run to six games, a new club record.
Potter admitted that all was missing from a fine performance was the goals.
“On the balance of the game we were the better team, created the better chances but on the key stat we ended up level which was disappointing.
“The overall performance was fantastic. We restricted a side with good attacking players to hardly anything, it's just disappointing it's only one point for us.”
Martinez denied Joel Veltman, Dan Burn, Leandro Trossard and substitute Danny Welbeck with some top stops and made nine saves in total, the most of his career.
“I think you have to give credit to the keeper who made some really good saves, but with a bit of luck we might have got a goal.”
Albion have claimed five clean sheets in the last six games, a statistic which pleased but doesn't surprise Potter.
“We've looked solid and kept their front four as quiet as you can. It's credit to our good defending as a team, we played very well.”
Villa boss Dean Smith was impressed with Albion.
“Credit to Brighton, they are a good progressive team well coached by Graham who gave us problems all night.”
