Porto midfielder Sergio Oliveira is interesting Stoke City.

TMW says the Potters, along with Crystal Palace, Palermo and Cagliari are suitors of the 24-year-old midfield man.

Stoke are now strangers to links with players from Porto, most recently been linked with striker Moussa Marega, but having gone one step further and loaned Bruno Martins-Indi and splashed out on record signing Giannelli Imbula in the last year.

Oliveira is far from a household name, playing just twice for his club side so far this season, and having played much of his football for Porto's B team.
