The Argentine international is looking forward to facing the England captain.
Everton have been chasing central defenders all summer, after they let Antolin Alcaraz and Sylvain Distin leave the club this summer.
That left them with just John Stones and Phil Jagielka in the heart of defence, woth some talented youngsters coming through.
In the end they did make a move, snapping up Ramiro Funes Mori.
The club, who confirmed a £9.5 million fee for the player, snapped up the defender from Argentine giants River Plate just before the transfer deadline.
Mori, who has earned two caps for the Argentine national team, has now been speaking about why he decided on the Premier League – and he mentioned a former Everton star in his explanation.
He stated to the official Everton website that his desire to test himself against strikers of Rooney’s calibre was paramount to his England switch:
“For me, it's the best league in the world.
“Since I was a kid, I've been watching the league. It's a very intense league, dynamic and obviously I'll have to adapt to that but it shouldn't take too long.
“There are lots of very big players who have played in this league, very important players like Wayne Rooney, Cristiano Ronaldo, a lot of others.
“To follow their steps is fantastic and I'm looking forward to testing myself against the attackers in the league.”
Everton know they have a real talent on their hands in Mori, who also already speaks English after living in the United States for seven years as a child, and that he will strengthen their current defensive options.
Whether he can get the chance to go toe-to-toe with Rooney when Everton face Manchester United next month we will have to wait and see.
