Edu impressed on debut in Gers' victory over Kilmarnock and said: "Pedro's a great player and it's good to play with him. He makes things a lot easier for me and I can learn a lot from his movement and his creativity.
"He could be the key to making me a better player."
Edu has been racking up the air miles playing for his country in recent weeks but he would not want it any other way.
He said: "Since I signed for Rangers, I've been to Guatemala, Toronto, Cuba and Miami. I've been everywhere with the national team and last month I was in China at the Olympics.
"I've picked up a lot of air miles but it's all for a good cause. We are going well and are only a couple of points shy of qualifying for the World Cup."
He added: "It's been a hectic time for me and I've been back and forth a few times but I'm here for a while now so hopefully that will help me settle in.
"I found the game much quicker here. The guys are more technical but it is also a real battle.
"The MLS is getting better all the time but you have seasoned veterans here, players who have performed in Champions League and UEFA Cup.
"My main aim is to sample that and become a better player. I also want to win championships with Rangers.
"That's what I'm here to do because I think we're capable of winning a few."
