"I have to talk to the coach (Diego Simeone) about playing in a number nine role, where Falcao played," Villa said.
"But I am simply at his disposal and will play wherever he wants. (Falcao) was loved here but hopefully I can make sure his absence isn't felt."
Briefly touching on his reasons for leaving Barcelona after three successful seasons, he added: "I left Barca because I wasn't playing, not because the World Cup was on the horizon.
"I love this game and I wanted to play it."
