Mikel Arteta has backed Bruno Guimaraes to "ignite something different" in Premier League champions Arsenal.
Brazil international Guimaraes was introduced to Gunners fans ahead of Sunday's 3-2 friendly defeat by Borussia Dortmund, after completing a move from top-flight rivals Newcastle reported to be worth £75 million ($101 million).
The 28-year-old has strengthened an already impressive midfield featuring featuring Declan Rice, Martin Odegaard, Mikel Merino, Martin Zubimendi and Eberechi Eze.
"You can see the immediate reaction," Arteta told Arsenal's website after Guimaraes was given an enthusiastic reception.
"I think he describes himself as a warrior," the Spaniard added.
"I think he's a warrior with a tremendous quality as well and intuition and leadership and charisma that is going to help us, that is going to really ignite something different in the team.
"I think he's going to push everybody inside the team as well and that's the type of player that we need."
