Arteta excited by Everton's Saha, Yakubu attack
"Yak is going to be a very important player for us from here until the end of the season," the Spaniard told evertonTV.
"We want him fit, we want him scoring goals - because we know with Yak fit this team is much better."
Arteta has also seen some encouraging signs of a burgeoning partnership between Yakubu and Saha.
"I think they are starting to understand each other," he added.
"There were maybe two or three flick-ons between them where they can score another goal or two, and I think they're putting in a better effort as well for the team so I am pleased with them."
