Second-half goals from Lucas Piazon and Denis Odoi secured Fulham's passage to the second round of the Carabao Cup with a 2-0 win at Adams Park.
Wanderers kept the Cottagers at bay for the first hour and created a couple of half-chances to open the scoring themselves, but came unstuck when Lucas Piazon’s superb strike from distance found the top corner.
Fulham’s progress was then secured when Denis Odoi headed home from Piazon’s corner, extending the Chairboys’ wait for a victory in this competition to a sixth year.
Gareth Ainsworth made seven changes to the side that drew 2-2 with Lincoln in Saturday’s opening league fixture, handing a professional debut to QPR full-back Jack Williams, while Fulham started with a completely different XI from the one that started in their 1-1 draw with Norwich.
As expected, the Championship side looked to impose themselves with some intricate passing play early on, though their unsettled side and some high energy pressing from the hosts meant that moves often broke down in the final third.
The Cottagers’ first chance came from a set piece, with Denis Odoi meeting Marcelo Djalo’s corner with a bullet header, only to be denied by a fine reflex save from Scott Brown.
Meanwhile for the Wanderers, their best chance fell to Max Muller at the back post, but he mis-timed his header from Joe Jacobson’s free-kick and saw the ball sail over.
Then Cauley Woodrow drilled into the side netting at the other end after latching on to a forward pass which bounced kindly into his path, only for the striker to aim for the near post and miss the target.
Fulham’s threat grew, and Denis Odoi went close again when he raced into the box to meet a pass and attempted a dinked finish over Brown, who was equal to it and tipped the ball behind for a corner.
His opposite number Marek Rodak needed to be alert to hold on to a speculative dipping drive from Michael Harriman as half-time drew nearer, and then Brown came to the rescue by clawing away Aboubakar Kamara’s cross which seemed destined to land at the feet of Woodrow.
There was to be no more action before the interval, with the entertainment provided by a flock of partridges which soared into the away end and set up camp in the Fulham half, narrowly avoiding a grisly death by either the ball of the foot of an unaware Rodak.
Nathan Tyson came on at the break in place of Paris Cowan-Hall, who’d picked up a knock in the first half, and as the rain began to fall, Woodrow mistimed a header from a teasing Matt O’Riley cross before side-footing wide moments later from a low cross from the left.
Tyson was close to reaching a Paul Hayes cross following a misplaced pass in the Fulham backline but Rodak narrowly beat the forward to the ball, and the eyes of the crowd lit up when Marcus Bean let fly with a snapshot from 15 yards only for the ball to fizz past the post.
As the game became ragged with neither side able to impose themselves in the middle, it took a moment of magic to break the deadlock, and it arrived on 67 minutes from the right boot of Lucas Piazon. The Chelsea loanee found a yard of space 25 yards, dead centre, before pulling the trigger and finding the top corner, giving Brown no chance.
Keen for a quick response, Gareth Ainsworth introduced Adebayo Akinfenwa from the bench with Paul Hayes making way, just after Tyson had skipped away easily from Michael Madl and won a corner with a shot from a tight angle.
The final change then came when Nick Freeman replaced Jack Williams, but the winger had little time to make an impact before Fulham’s second goal arrived.
There were just nine minutes left on the clock when Odoi met Piazon’s corner with a glancing header which flew past Brown and into the net.
Akinfenwa looped a header over the bar moments later as Wycombe looked for an unlikely comeback, and then a loose ball fell into the path of Matt Bloomfield but his left-footed strike swerved wide from the edge of the box.
Tyson saw a late header tipped behind by Rodak following Jacobson’s free-kick before Odoi and sub Ryan Sessegnon attempted to stretch the lead in stoppage time.
2-0 was how it finished though, as Wanderers turn their attentions back to league matters with the visit to Port Vale on Saturday.
