Futbolarena report that Everton are prepared to activate his €8.5 million release clause.
Nani has been one of Portugal’s stand out performers at Euro 2016 scoring twice for his side including today in the 3-3 draw against Hungary which helped book a place in the next round.
The Portugal international is currently the joint top scorer for his national team alongside Cristiano Ronaldo.
Everton could face competition from Premier League rivals Manchester United if reports from Turkey are to be believed.
United are reported to have agreed personal terms with Nani according to Turkish media outlet DHA.
The Red Devils are however, reported to be reluctant to match his release clause considering Nani was sold for less to Fenerbahce last season.
Nani joined Fenerbahce on a three-year deal from United last season and scored 12 goals while providing 13 assists last season.
