Valencia defender Aymen Abdennour has reportedly attracted interest from both Everton and Newcastle United.
Abdennour has spent the last two seasons at the Mestalla, but he has made just 43 appearances in all competitions during that time.
According to Foot Mercato, he is one of a number of players who could be allowed to leave the La Liga outfit during the summer, and that is said to have alerted both the Toffees and the Magpies.
Newcastle have a number of options at centre-back, but boss Rafael Benitez is allegedly keen on adding quality over quantity ahead of their return to the Premier League.
It has been claimed that any club interested in the 27-year-old will have to pay €15m (£13.13m).
