Goals from Ryan Tafazolli and Sam Vokes ensured Gareth Ainsworth’s side take the advantage into Sunday’s second leg at Stadium MK.
In a performance not akin to one Dons fans have seen of late, here’s how we rated the players at Adams Park.
5. Daniel Harvie - 6.5
Was Dons' liveliest outlet in the opening half-an-hour when running with the ball but his impact faded soon after Photo: Jane Russell
6. Kaine Kesler-Hayden - 6.5
Like Harvie, had a good opening half-an-hour and didn't shy away from mixing it with a physical Wycombe side. Probably Dons' biggest threat in the second half. Photo: Jane Russell
7. Top Don: Conor Coventry - 6.5
Fought and scrapped for every ball but was just overrun by the sheer number of bodies Wycombe packed in the middle of the park. Photo: Jane Russell
8. Josh McEachran - 5
Matched Wycombe's physicality but lost his head after getting booked, earning his second not long after and leaving Dons in a hole for the final 21 minutes. Photo: Jane Russell
