Everton are reportedly considering a summer swoop for Porto centre-back Bruno Martins Indi.
The Toffees are expected to lose England international John Stones in this transfer window, with Manchester City said to be increasingly confident of bringing the ball-playing defender to the Etihad.
According to The Sun, Everton boss Ronald Koeman has drawn up a list of targets and among them is Martins Indi, who is believed to be valued in the region of £12.5m by his Portuguese club.
The 24-year-old, who can also play full-back, joined Porto from Feyenoord in 2014 and has made 71 appearances across two seasons for the Primeira Liga outfit.
Manchester United were linked with a move for the Dutchman when Louis van Gaal was in the hotseat.
