On Saturday, a stream of ticket-holders left the tennis club for nearby pubs to watch England's triumphant quarter-final after Wimbledon bosses opted not to show the game on the big screen, while others gathered around iPads and phones on site.
Some 44 per cent of United Kingdom said they won't be watching the Men's Final at all on the Sunday due to Andy Murray's absence from this year's competition.
When asked if he thought people watching the World Cup final on their devices simultaneously would detract from the atmosphere, Federer added: "It's going to happen anyway, if I'm going in the final or not, the Wimbledon final will take place, and so will the World Cup final".
Though the World Cup is likely to draw a bigger TV audience, a lot of us would be disappointed to miss the Wimbledon final.
The men's singles final, scheduled to begin at the traditional time of 2pm on Sunday, will not be moved to avoid a clash with the climax of the football tournament, organisers have confirmed.
But Wimbledon chief executive Richard Lewis stuck to his view that spectators coming to the grasscourt championships expect to see tennis and said that big-screen policy will remain in place to limit the disruption caused to players.
Despite the possible clash, with the World Cup final due to kick off at 4pm, Mr Lewis said the stands would be "packed" and spectators could use "modern technology" to follow the football at the same time.
With England still in contention to reach the final in Moscow, it has been suggested the football tournament could prove a significant distraction as fans at Wimbledon try to keep up with events in the Russian capital.
"We didn't have one single complaint of anybody here feeling that the football interfered with their enjoyment of Wimbledon", he said.
"We are a sold-out event and there's massive interest", he said.
Club rules that all mobile phones and tablets should be switched off "in and around the courts of play" have been relaxed, however, with Lewis stating that they would only be enforced if they affected others. "They'll hear every point, wow, love-15, 15-30", he said.
I was out and about around the grounds and you could tell when England had scored and it was lovely, it was wonderful.
