Celtic's chances of bringing back Jason Denayer next season hang in the balance, according to a report in the Manchester Evening News.
The paper write that Manchester City are impressed with Denayer's progress, with the defender linking up with captain Vincent Kompany at international level with Belgium this week.
Just as important for City, is the factor Denayer would qualify for their quote of homegrown players, an area where the club have faced challenges to meet criteria previously.
Whether they keep Denayer however depends on how he fares in pre-season. It is reported that he will be considered against another loanee for a spot in City's squad at centre-back.
The player in question is PSV's Karim Rekik, who is on a season long loan from the club. The 20-year-old has made 29 start for the Dutch side this season and will be feeling equally as buoyant as Denayer about his chances of kicking on for City.
The report states: "Denayer could end up fighting for a place with Rekik, who has also had another successful loan spell at PSV Eindhoven, who sit proudly on top of the Dutch league."
One factor against Celtic, is a line in the report which states PSV have already held talks with City about extending Rekik's loan by another year, which Manuel Pellegrini's side would only approve if they were happy with Denayer.
For Celtic it would be a tough blow to lose him, albeit not one which would take them entirely by surprise. Yet with Virgil van Dijk in-demand too, a big challenge could be ahead for manager Ronny Deila to re-shape his defence this coming summer.
