Odegaard finished last season fit and went on to shine at the World Cup with Norway.
He started five of Norway’s six games in the tournament and registered four assists.
“Last year was really a big struggle with a lot of difficult moments. To miss so many games because of injury was really frustrating,” Odegaard said on Sunday.
“It is the worst thing for a footballer to not be able to be on the pitch and I had quite a lot of weird injuries, and bad luck.
“It was good for me to end the season with a title, here, and then a good World Cup. Then I had my break and I feel good, ready to go again.”
“What I have just worked on is to use that as motivation for this year and to come back stronger. And to use all of those experiences in a positive way.”
Odegaard and Guimaraes appeared to click straight away in their first start together.
“Sometimes you are just in the flow. You need to find that on the pitch,” Odegaard said of his performance.
“All of us were flowing pretty good out there. I will just try to keep that up and keep going.”
And Arteta said he was looking forward to having Odegaard fit and available heading into the new season.
“Well, he missed five or six months for different things and it was extremely difficult for him to get any momentum,” said Arteta.
“So I’m sure this year if we can maintain him fit, available with the players around him, we’re going to see a very different Martin.
“And I sense from the first day that he joined [pre-season training] that he has something else on the belly that he wants to prove and show, because the team needs it as well.”
