"All our English teams are way off this standard," he told BT Sport.
"Chelsea are the nearest, they have a real settled team and their first XI is a real, genuine first XI. I think Jose Mourinho is still searching for his first XI, he's still not sure of a few players. This summer will be huge for them."
Ferdinand was quick to point out what he believed was the cause of the perceived gap.
He added: "I just feel like the English teams are in transition all the time,"
"They change a few little nuances every year. In England it's "Oh we've had a bad season, let's rip it up and start again.
"We seem to be chasing all the time. We need a little bit of patience with the managers, we need to keep all of our better players.
"The better players never leave here, or at Juve. When we get a star man in the Premier League – Chelsea and Eden Hazard, it's "Real Madrid want him. " Coutinho, oh "Barcelona want him". They're looking over their shoulders all the time."
