Everton midfielder Idrissa Gueye has put pen to paper on a new long-term deal at Goodison Park that will see him remain at the club until the summer of 2022, but does that spell the end for a fellow teammate?
Gueye, 28, originally had another two and a half years remaining on his previous deal after signing a four-year contract when joining the Toffees from Aston Villa in the summer of 2016.
But Sam Allardyce has decided to extend the Senegal international's stay at Goodison Park, keeping him well into his thirties unless the former Lille midfielder is the subject of a transfer beforehand.
Gueye has been a mainstay under Ronald Koeman, David Unsworth and Allardyce, missing just three of Everton's 27 Premier League outings this season and is widely considered the best central midfielder at Goodison Park.
The faith shown in Gueye could worry a couple of Everton's squad who are further down the pecking order, and none will be feeling the pressure more so then Muhamed Besic who is currently on loan at Middlesbrough.
The tough-tackling midfielder, 25, will be unsure of his long-term future at Everton anyway after suffering a long-term knee injury before being loaned to Tony Pulis' Championship side.
He is below the likes of Gueye, Morgan Schneiderlin, James McCarthy, Tom Davies and Davy Klaassen in the Everton pecking order and could be made surplus to requirements.
The Bosnia international has made an impressive start at Boro where he will remain until the end of the season, and a string of decent performances could tempt Allardyce to keep him.
He has three and a half years still to run on his Everton contract, which the Daily Star claim is worth £30,000 a week, but the likelihood is that Gueye's new deal is only going to push Besic closer to the exit door.
