Trezeguet scored the only goal as Aston Villa moved out of the relegation zone on goal difference with a 1-0 victory against Arsenal at Villa Park.
The result means that Dean Smith's side travel to West Ham United on the final day with their Premier League destiny now in their own hands after Watford dropped to 18th following their 4-0 loss to Manchester City.
Trezeguet rifled home his third goal in as many matches after 27 minutes when Conor Hourihane's corner was flicked into his path by Tyrone Mings.
Moments after Villa substitute Keinan Davis fired a great chance for a second wide, Arsenal nearly found an equaliser when Eddie Nketiah's 77th-minute header came back off the inside of the post before bouncing kindly into Pepe Reina's hands.
But Villa held on to climb up to 17th. Arsenal remain 10th on 53 points, with their top-six hopes coming to an end.
