Seaman feels Arsenal do need to make a new striker signing in January.
"I would imagine that Arteta would be looking at it [signing Ivan Toney in January]," Seaman told The Sports Daily.
"People were asking why they needed a striker like that. They were already scoring the most goals in the league and winning the title without him, but then you see the impact he had.
"A big target man like him, who guarantees goals could certainly work at Arsenal."
