Former Arsenal forward Alan Smith has questioned the Gunners' motive for wanting to sign Chelsea star Willian.

The Brazilian is expected to be announced as an Arsenal player this week after he confirmed he is leaving Stamford Bridge after seven years.

The 32-year-old will put pen to paper on a three-year deal worth £150,000-a-week.

Arsenal are looking to strengthen their attack going into the new season, and Smith is hopeful Mikel Arteta will get the best out of Willian.

But the Sky Sports pundit has questioned whether the Brazilian is actually an Arteta signing, or whether he is being snapped up for business reasons.

"It is time to move the project forward by adding quality in certain positions, which is not easy at all when money is tight," Smith told  Sky Sports.

"Willian's free transfer from Chelsea looks like the first step, which surprised me at first given the Brazilian's age.

"Just turned 32 with lots of miles on the clock, Stamford Bridge has surely seen his best days.

"So was this just a convenient move because he has the right agent? Something foisted upon Arteta by Raul Sanllehi, the head of football?

"Or does Arteta see something in Willian that can improve the team straight away?"

Willian's agent is Kia Joorabchian, an Arsenal supporter who shares a good relationship with Gunners technical director Edu.

Joorabchian is also the agent of Philippe Coutinho, who has been linked with a move to Arsenal in recent weeks.
