Ze Eduardo, who spent last season at Genoa, has struggled with injury during his time in Italy, blaming the cold weather, and is delighted to be moving back to Brazil.
“I am to all intents and purposes a Vasco da Gama player now,” the former Palmeiras forward told Mediaset.
“There are no problems with the transfer and I can’t wait to get my form back.
“Before coming to Italy I never had injuries, but due to the cold weather I’ve consistently had problems.
“This is why I’m happy to be going back to the warmth of Rio. I want to play because, like so many, I dream of a place in the Selecao for the 2014 World Cup. I am a Vasco player now and I feel happy.”
Vasco are looking to revamp their squad during the Brazilian close season after losing veteran stars Juninho and Felipe in the past week and see Ze Eduardo as an ideal replacement.
The 25-year-old made just nine appearances whilst on loan for Siena, scoring twice.
