According to a report from O Jogo (translated by SportWitness), Sporting are also keen on signing him on loan for another season.
It will be interesting to see if the Premier League side make their move for the Guangzhou Evergrande midfielder in the coming weeks.
Gudelj was on loan at Sporting this past season and he had an impressive campaign with the Portuguese side.
Newcastle’s interest in the player certainly makes sense.
They need to improve their central midfield options with Hayden expected to leave. Gudelj could be the ideal replacement.
