Sunderland manager Gus Poyet has revealed why he did not sign his son Diego Poyet this summer.
The striker moved to Sardinia on a permanent deal last summer after spending the previous season on loan with the Rossoblu but will now return to Brazil for family reasons.
"After more than two years with the Rossoblu, I leave Sardinia to return to Brazil and play in Santos," he told www.cagliaricalcio.net.
"It's a difficult decision, because I consider the Cagliari an important team with special fans. To them I extend my greetings.
"In Sardinia, I found love, respect, friendship from everyone: from the President Cellino, who always treated me with utmost respect, to team-mates, not to mention the technical staff as well."
