Whilst much of the focus has been on incomings at Everton this summer, with Hayden Hackney and Tyrique George both arriving, the Toffees are now facing their first real exit concern.
It's a worry for David Moyes, who is at the start of building a project which he hopes will end in European qualification. The last thing that he needs is to lose a current star, especially the young players in his squad.
That's why PSV's interest in Adam Aznou will come as a concern. The former Bayern Munich man arrived last summer and barely got a look in, but it's worth noting that he's still just 20 years old. The future is bright, but may not lie at the Hill Dickinson.

Aznou is yet to even make his mark in the Premier League, but that's not stopping PSV from targeting an unexpected swoop.
PSV prioritising move to sign Adam Aznou
According to Africa Foot, as relayed by Sport Witness, PSV are now prioritising a deal to sign Adam Aznou and their interest is 'very real'. It's a huge concern for the Toffees, who should be doing everything to keep a player with plenty of potential.
Adam Aznou for Everton
Yet to make real first-team impact, the former Bayern Munich man has been forced to be patient, but could enjoy the reward of several starts next season when competing with Vitalii Mykolenko.
If PSV's interest turns into an offer, then it will be interested to see whether Everton face a fight on their hands. For now, however, they will be telling Aznou that good things come to those who wait.
Dubbed "fantastic" by scout Jacek Kulig, no one os doubting the 20-year-old's potential - especially as PSV's interest emerges.
