In his column for The Sun, Wright argued: "A club needs at least two world-class strikers to win the Premier League title.
"Ideally, they should have three top-drawer players.
"So I would like to know how on earth Rafa Benitez thinks he is going to crack the championship with just one top striker.
"Benitez has been unable to attract a top-class second striker like David Villa. He fought with the club's owners to have total control in the transfer market but has not addressed a blindingly obvious issue.
"Those teams will now see Benitez's side as both weak and beatable."
