Trezeguet's double boosted Aston Villa's hopes for survival as they won for the first time since January, beating Crystal Palace 2-0 at Villa Park
Palace thought they had taken the lead through Mamadou Sakho early on, but VAR ruled the strike out for a handball, before Trezeguet put Villa ahead in first-half stoppage time with a finish at the far post (45+5)
Villa impressed in the second half and doubled their lead through the Egyptian again, poking under Vicente Guaita (59) from eight yards, and they held on with Palace offering very little in the final third as they stumble towards the end of the season
To make matters worse for Palace, former Villa man Christian Benteke was sent off after full-time for an off-the-ball incident with Ezri Konsa
The result means Villa are four points from safety with three games remaining, but with a vastly inferior goal difference to both 16th-placed West Ham and Watford in 17th
 Palace, who have now lost five on the bounce, are in 14th
VAR was dominating again as early as the seventh minute as Sakho touched home Luka Milivojevic's free-kick ahead of Pepe Reina, with the Stockley Park officials ruling it had hit the defender's arm, though Palace will claim it hit his shoulder
Villa were dealt a blow just before kick-off as the injured Kortney Hause was replaced by Ahmed Elmohamady, but the Egyptian nearly set up the opener as his fine cross was headed over by Mbwana Samatta in space
Both goalkeepers were busy as Guaita stopped Jack Grealish's volley from another good Elmohamady cross, before Reina denied former Villa man Christian Benteke with a low block at the other end
But deep into the lengthy stoppage time added on for the VAR review, Villa took the lead
 Conor Hourihane's dangerous free-kick from the left was only half-cleared by Joel Ward, and Trezeguet arrived at the back post to control his effort beyond Guaita from close range
Villa continued to press after the break, and thought they had a penalty as Grealish went down near Patrick van Aanholt's challenge, but again VAR intervened, with replays showing the Villa man had actually initiated contact
The goal was coming - Hourihane's free-kick was tipped wide by Guaita, before Konsa's point-blank touch was again cleared off the line by the goalkeeper before Villa's second - and it came again through Trezeguet
 John McGinn's cross for Grealish was cleared as far as Hourihane, the midfielder's header back into the box found Trezeguet unmarked, and his first touch on the stretch allowed him to poke under Guaita with his second
Van Aanholt nearly halved the deficit, Reina blocking his low shot well with 15 minutes remaining, but Villa came closest to getting the game's third goal, as Trezeguet and Davis both came within inches of latching onto Matt Targett's left-wing delivery
And Palace's day got even worse after full-time as Benteke was sent off by Martin Atkinson for an incident with Villa defender Konsa
Villa have lost more points from winning positions than any other Premier League team, but were able to see the game out for a much-needed win to give them a glimmer of hope, while Roy Hodgson will be worried as five straight defeats sees Palace crawl towards the finish line
Villa boss : "It's felt a while since I had a big smile! It's really big
 It's the first leg of a semi-final, and we've managed to win that, and we've got a second leg at Everton
 It was a good performance and I think we deserved it today; we were worthy winners
"It was a more attacking line-up today; we felt we'd have a lot more of the ball than we have against Liverpool and Man Utd, and it paid dividends
"It gives everybody a big lift
 Our performance since lockdown has been really good, that's our second clean sheet, defensively we've been better, and now we've scored some goals, which we needed to do, and created some chances
"Palace boss : "We put ourselves on the back foot going into half time
 When the second goal went in we gave ourselves a mountain to climb, and quite frankly I never thought we looked like climbing that mountain today
On Benteke's red card: "It's inexcusable, basically, that's the bottom line
 There was a lot of niggling going on on the field, we're close enough to be aware of that, but the thing is that is part and parcel of the game we play, it is quite often present in a lot of football matches
"And you must not allow it to provoke you into doing something that is going to stop you playing for the rest of the season
 Christian Benteke just came back into the team, is playing his fifth or sixth game in a row, which of course he wasn't doing before football was halted, and it was a great opportunity for him to finish the season by getting these games under his belt, and now he's going to miss them
"He's unhappy about that, of course, as we are, but unfortunately I can't excuse it, no matter how provoked he may have been, no matter what might have been said
 You know that when you kick out at an opponent, and the referee sees it, you get sent off
 That has been happening in football for as long as I can remember
 All Christian can do, I guess, is apologise to his team-mates and accept his punishment
"Villa now go to Everton on Thursday at 6pm, live on , before hosting Arsenal on July 21, also live on  at 8
15pm
 They finish the season at West Ham on July 26
Palace host Manchester United at 8
15pm on Thursday, before going to Wolves on July 20, and hosting Tottenham on the final day of the Premier League season on July 26
