According to The Mirror, Southampton are increasingly concerned that Ronald Koeman could leave the club, with Everton believed to be interested.
Koeman, 53, arrived as Saints boss back in the summer of 2014, as his impressive spell in charge of Feyenoord handed him the chance to replace Mauricio Pochettino on the South Coast.
The Dutchman immediately saw the likes of Rickie Lambert, Adam Lallana, Luke Shaw, Dejan Lovren and Calum Chambers all leave the club, but remarkably managed to rebuild the side, guiding the Saints to a seventh-placed finish and subsequent Europa League qualification.
Again, Koeman lost key players last summer with Toby Alderweireld, Nathaniel Clyne and Morgan Schneiderlin all leaving the club - but again, he's battled through and currently has Southampton up in seventh place again having beaten Manchester City 4-2 on Sunday.
Now though, The Mirror report that Southampton are concerned that Koeman will look to leave the club, despite opening talks over a brand new five-year deal for him to stay.
It's claimed that Everton are building their interest in Koeman, with their manager Roberto Martinez under huge pressure after an underwhelming season at Goodison Park - and with just one year left on his deal with Southampton, Koeman could be tempted to leave for a good enough offer.
The report also suggests that Arsenal are keen on Koeman if Arsene Wenger leaves, but Southampton will again try to secure a new contract with their impressive manager this summer, and will be hoping to fend off their Premier League rivals.
Do you think Koeman would leave Southampton for Everton?
