Everton manager David Moyes has expressed his delight at the form of defensive trio Phil Jagielka, Johnny Heitinga and Sylvain Distin ahead of Saturday's match at Norwich City.
Seven clean sheets in their last 12 matches have helped the Toffees move above local rivals Liverpool into seventh place in the Premier League table.
"We've never been in a situation where rotation has needed to be done because we've never really had a backlog of fixtures, but we have had for the last three weeks," said Moyes.
"Now I have got three centre-halves who are playing very well. I've got one who plays for Holland who are ranked number two in the world, I've got one who plays for England and I've got Sylvain Distin who has been fantastic and gives us a natural left footer. So I've got real good competition with the form they're in."
Leon Osman's late goal earned Everton a 1-1 draw with Norwich at Goodison Park in December.
