Emiliano Martinez made more saves than he has in any Premier League match to deny Brighton victory, as Aston Villa held on to draw 0-0 at the Amex Stadium.
Martinez produced a flying fingertip stop to keep out Dan Burn's first-half header, but saved his best work for after the break to frustrate a familiarly profligate Brighton side.
Deflected efforts from Alexis Mac Allister and Joel Veltman had the Argentinian at his very best before he also kept out substitute Danny Welbeck's close-range effort late on as he made nine saves in total.

Man of the match: Emiliano Martinez
Martinez the hero as Brighton suffer old issues
With goals still a premium despite their recent upturn in form, Brighton boss Graham Potter would have been encouraged to see the conviction with which his side started, with Mac Allister heading wide a lovely cross from Veltman.
Intention was never lacking from the hosts, but attacking quality was still at a premium. Despite registering 12 shots before the break, only Burn's header from a corner forced Martinez into any real difficulty.
"Brighton don't finish teams off. What happens, they'll get hurt second half, with a bit of quality from Aston Villa," Sky Sports' Micah Richards said at half-time.
In the first period, Brighton had restricted their hosts to a solitary shot. Within a minute, Villa fired a warning that they may have re-emerged a different side with Barkley firing straight at Robert Sanchez from 20 yards, but it never manifested into anything more.
Instead, Brighton picked up where they left off. Mac Allister's deflected shot was smartly saved by Martinez's legs, before he was again at his best as another ricochet took Veltman's effort towards the top corner, where it was met by a firm glove from the 'keeper.
Brighton substitute Welbeck nearly found a way in when Tyrone Mings' poor clearance was pounced on and the ex-England striker was denied by Martinez, who put his body on the line to keep him out from close range.
What the managers said...
Brighton manager Graham Potter: "It should have been three [goals], on the balance of the game. We created more chances, we pretty much did everything more, but on the key stat we were level. But the overall performance was fantastic against a team with a lot of attacking players, and we restricted them.
"If we play like that, we'll pick up points in this league. We look solid. Again it wasn't just a defensive display, we attacked well and had courage with the ball. I thought we were the better team and did everything but score."
Aston Villa manager Dean Smith: "We weren't even bang average. I've never seen us make so many unforced errors, we just kept giving the ball away from start to finish. It was sloppy. But we showed resilience to keep the ball out of the net.
"It was disappointing all round, the only thing to come from it is a clean sheet and resilience we've shown. [Martinez] made some good saves when needed, and was our best player on the pitch tonight.
"We've not had too many performances like this where we've been second best, but thankfully a point and a clean sheet. It's another point to the tally but we're disappointed with our performance tonight."
Man of the match - Emiliano Martinez
Sometimes, picking a man of the match is a tough call. Not here. Martinez was the star of the show to earn Aston Villa a point they otherwise barely deserved.
His saves in either half were often routine, but on occasions needed some real quick thinking - including a second-half pair of saves from deflected efforts which could easily have caught him out. "He was our best player," said a relieved Smith after the game. It wasn't even close.
