Aston Villa grabbed a priceless Premier League survival lifeline, beating Arsenal to climb out of the drop zone with one match to play.
Trezeguet netted a crucial winner to clinch a 1-0 victory which lifts Villa out of the relegation zone for the first time since February.
The winger set up a dramatic finale on Sunday with Villa, Watford and Bournemouth locked in a three-way battle against the drop.
Dean Smith’s side are now above of the bottom three on goal difference ahead of Sunday’s trip to West Ham, who are out of danger thanks to their own superior goal difference.
For Arsenal, they will need to rely on an FA Cup win next month to return to Europe and could finish as low as 10th in the Premier League.
The Gunners hit the post through Eddie Nketiah but never found the form which saw them beat Liverpool and Manchester City in their previous games.
You have to go back to 1998 for the last time Villa beat Arsenal at home, where Dion Dublin was amongst the scorers, and Steps were number one in the charts.
Back then Arsenal were champions but the title feels a long way away for the Gunners despite the promising early signs of Mikel Arteta’s debut season.
A plane towing the message ‘Back Arteta Kroenke Out’ served as a reminder of the anger felt by fans with the Gunners facing a fourth season outside the Champions League, having not won the title in 16 years.
The noise of the aircraft almost drowned out the players in an empty stadium which did little to spark the game in a low tempo opening 20 minutes.
But out of the blue the hosts made the decisive breakthrough in style after 27 minutes.
Conor Hourihane’s corner missed everyone except for Trezeguet who was loitering at the far post and the winger drilled in a brilliant low strike from 15 yards.
Villa kept the Gunners at bay though and should have made it comfortable with 15 minutes left.
Grealish glided past two challenges to send Keinan Davis clear but the substitute dragged his shot agonisingly wide.
A minute later Nketiah’s header hit the post and spun back fortuitously into Pepe Reina’s arms.
Emiliano Martinez beat away John McGinn’s fierce drive at the other end as Villa nerves began to grow – but they held on.
Final score: Aston Villa 1-0 Arsenal
