Both London giants have been linked with Coutinho, currently on-loan at Bayern Munich.
Ferdinand said: “Would he improve Spurs?
“Yes he would, 100 percent. People like Kane, Dele, Son etc. all feed off someone like him.
“I think he would be a great addition to Spurs’ squad. Arsenal he would definitely improve them, but where does he play in their system?
“They’ve got Ozil. I like Ozil if he is played well.
“Barely any team can afford him where he would fit in.”
