Newcastle manager Rafa Benitez is reportedly seeking to bring in an experienced head in Iker Casillas to England in January, according to Portugal publication Jornal de Noticias.
The 36-year-old has found himself on the periphery at Porto, and is now being viewed as a great fit for Newcastle.
Casillas spent 16 years at Madrid, garnering five league titles and three Champions League winner's medals, also winning the World Cup and two European championships with Spain.
At 36, the Spaniard is still at a decent age for a stopper, and given his status at his current club, he could be keen on a move next year.
As much as Newcastle might want to get him on their books, they are said to be unwilling to match the £95,000-per-week he nets at Porto.
Benitez is reported as wanting to send Freddie Woodman out on loan in January and bring in a third senior keeper. The manager is also said to have approached Willy Caballero and Pepe Reina during the summer, but Caballero joined Chelsea, while the latter stayed put at Napoli.
Rob Elliot and Karl Darlow have been trading the space between the sticks for the Magpies this season. And Casillas arrival would definitely spark huge competition.
Benitez, meanwhile, quizzed over his January plans, simply revealed that his mission is to keep his team up.
"The priority is to stay in the Premier League - not find the next best player for the next 10 years," he told reporters.
"We must make sure we have what we need to compete. We have to consider every option and see it's for us or not."
