Arsenal fans, then, will have a particularly keen eye on this World Cup last-16 showdown as their club captain goes head to head with the man who could take their midfield to the next level.
The Gunners will already be favourites to retain their long-awaited Premier League title next season, but the addition of Guimaraes might just wrap it up before a ball has been kicked. Signing Spain's Martin Zubimendi last summer was one thing, but having Bruno alongside Declan Rice and Odegaard in the middle of the park is quite another.
That trio is a mouth-watering prospect; Rice would continue to operate as a defensive-minded, box-to-box shuttler, Guimaraes can chip in with the dirty work, hard running and creativity as a No.8, and Odegaard would be freed to create at the top of the pitch, in the knowledge that his side are in safe hands in transition and without the pressure of striving to end his club's wait for a title.
Some might have thought that the Brazilian's arrival would spell the end for his Norwegian counterpart at the Emirates, but both are proving at the World Cup that they can be a huge part of Arsenal's future as Mikel Arteta looks to build an era of domestic dominance.
