The Welshman, who was labelled a "unique freak" by Sir Alex Ferguson following the championship-sealing victory over Aston Villa on Monday, has now extended his own record in lifting the most English titles.
"If you look at the amount of wins we have had, you have to recognise it has been a brilliant season in the league," he said.
"Some of the performances have been superb.
"Whenever you win the Premier League it is something special.
"Obviously, if you look at the end of last season that was a huge disappointment.
"To come back the following year and perform so strongly means it must rank really high.
"Overall, we have to be happy with the way it has worked out."
