Vijender has won all his four bouts via Technical Knockouts in under three rounds.
But in Royer, he faces a rival who has the experience of 44 bouts, including 14 wins, which adds up to 250 rounds in the ring compared to Vijender's nine.
Royer's career spans over seven years and he will be looking to spoil the party for Vijender when he makes his second appearance on UK soil.
"From whatever I have seen of him, he does not look easy. He knows how to fight a tough one. I would say he is good but then I am no less," the 30-year-old said.

"I will try to finish this fight as soon as possible again. But I think it could be a little longer than the previous ones, which is also good for me," he added.
"I have heard a lot about Vijender's amateur career and his winning start in pro boxing. It will be an amazing fight with a lot of competition between both of us. I am fully prepared to give tough time to Vijender and I am sure I will be able to put an end to his winning habit tomorrow," he said.
Tomorrow's bout will be televised live by Star Sports 2 and Star Sports HD 2 from 10:30pm (IST) and on Star's Digital platform, hotstar.
