The Three Lions were disappointing in the first half against the Swiss opposition. But they rallied in the second half and secured the win thanks to a 54th minute goal from Marcus Rashford.
And Maguire gives the manager credit for the win.
Maguire told Sky Sports: "There were a few words spoken between the boys.
"We all weren't happy with the performance, we gave them too much respect with the ball. The pressing was in bits and bobs, people were going and people were staying, so the gaffer had stern words with us and the second half was much better."
