A stunning four-minute hat-trick from Jon-Paul Pittman gave Wycombe a 5-1 win against a Chelsea XI, with Scott Rendell and Ben Strevens also finding the net after Aliu Djalo's opener for the visitors.
The first goal came when Nikki Bull made a fine save to deny Scott Sinclair but the rebound was turned home by Djalo on 13 minutes.
But the equaliser arrived after a spell of Wycombe pressure and Scott Rendell fired home from eight yards after the ball fell kindly to him following a challenge by a defender.
And Strevens stroked the ball past keeper Sam Walker from a tight angle after an intricate move from the home side, culminating in Keiran Murtagh's clever flick and Strevens' tidy finish.
Pittman then scored three times in four minutes to stretch the lead to 5-1, firstly firing under the keeper from Kevin Betsy's pass and then tapping home after stunning work from returning winger Matt Phillips, before chipping home exquisitely a la Lionel Messi to cap a confident and stylish victory.
