Manchester City defender Danilo has reportedly emerged as a transfer target for Porto.
Danilo only signed for City during the summer transfer window, but the versatile full-back has made just seven starts in the Premier League and Champions League this season.
City boss Pep Guardiola is currently struggling for fit defenders but according to The Sun, that will not stop Porto from making a loan bid in January.
The 26-year-old is no stranger to the Estadio do Dragao having made 119 appearances for the club between 2012 and 2015, with his performances eventually leading to a transfer to Real Madrid.
Porto currently sit joint-top of the Primeira Liga table with Sporting Lisbon.
