Norwich City Under-23s ended their 2018-19 pre-season schedule with a 3-2 victory over Dereham Town at Aldiss Park.
Adam Idah netted for the Canaries early on with a neat finish and they went onto control the first-half, although Dereham equalised against the run of play through a Danny Beaumont free-kick.
Adam Hipperson gave Dereham the advantage at the beginning of the second-half before Spyrou equalised for City with 15 minutes remaining.
Spyrou then grabbed his second and City's third with just a couple of minutes left on the clock to ensure the Canaries ended their pre-seaon with a win.
City had the better of the first-half and looked very comfortable in possession, although chances to score were not as frequent at Matt Gill would have liked.
Early on Devonte Aransibia struck crisply from distance but his strike was well held by the Dereham stopped.
The first moment of real quality saw City ahead on 11 minutes. Spyrou and Idah linked up on the edge of the box with the Irishman latching onto his strike partner's delicate through ball to dispatch it past the goalkeeper emphatically.
City continued to force the issue and Aransibia was key to everything going forward from midfield. On 24 minutes he picked the ball up on the half-turn and shot low and hard but the ball just missed the goalkeeper's right-hand post.
Dereham had rarely threatened a goal in the first-half but they managed to sneak an equaliser with only five minutes of the half remaining. Beaumont curled a free-kick through the wall and it managed to beat the clutches of Jon McCracken.
The hosts caught City off guard in the early second-half minutes and took the lead spectacularly when Hipperson rifled the ball in-off the crossbar from 25 yards.
The general rhythm of the game following City going behind continued as they still dominated possession, however Gill's side had much more purpose about their play.
Caleb Richards had been a real threat from the left flank with his crossing and his latest delivery on 56 minutes was met by Spyrou but he nodded over.
Gill introduced Josh Coley in an attempt to stretch the game and the change almost reaped instant rewards when the winger connected with another Richards cross. However, he couldn't keep his volley down from a few yards.
Then Aransibia went close from range once again, forcing a brilliant stop from the Dereham stopper, before City almost shot themselves in the foot at the other end when Ciaren Jones' heroics on the goalline kept the deficit to just one.
Jones then showed his quality at the other end, splitting the Dereham defence with a accurate through ball, allowing Spyrou to control and finish brilliantly to equalise.
Coley went close to grabbing a winner for City in the closing minutes as he just missed the keeper's far post with a curling effort but moments later the Canaries did indeed snatch a third.
Idah did well to force the goalkeeper into the mistake and that allowed Spyrou to thump home his second of the game to take the win.
