Devenny impressed as Palace made a fast start in their final game at the Como Cup – the Eagles scoring twice inside the first ten minutes.
The Northern Ireland international was able to convert after some superb link-up play.
Flicking the ball round the corner to play in Rio Cardines, who teed the ball back to the midfielder, Devenny then finished coolly at the near post.
It was a goal that showed Palace at their best, with another excellent team move ending with Eddie Nketiah sweeping home a second just nine minutes later.
