However, Ferdinand is confident that there is enough quality at the club to see the team challenge on all fronts.
"We've got a strong enough squad to win everything," the 34-year-old told the Evening Standard. "We won the League at a canter last season and we've not become a bad team overnight. We believe strongly in what we've got. And anyway, you can't judge the league after three games. We'll have to wait and see where we end up."
United continue the defence of their Premier League title on September 14 when they play host to Crystal Palace.
