Celtic are trying to convince Manchester City to allow Jason Denayer to join up for a second spell at Parkhead, but their efforts could prove fruitless.
If Manchester City do not allow Jason Denayer to rejoin Celtic on loan next season then the Scottish club shouldn't look far for his replacement.
Celtic boss Ronny Deila has admitted in the Glasgow Evening Times that he is hoping to convince City to allow Denayer to have a second season at Parkhead, but there have been suggestions that the Belgian international has a first-team future with the current Premier League champions next term.
City are looking to freshen up their squad and they could look to Denayer to push for a place in their senior side in the near future.
That would be a disappointment for Celtic, but there is a ready-made replacement for the 19-year-old, and he is also at the Etihad Stadium.
Karim Rekik has been sent out on loan over recent years and he looks to possess a similar skill-set to that of Denayer.
The 20-year-old, who is currently at PSV Eindhoven, is excellent in possession, but he is also is a commanding defender and he looks to have a huge amount of quality.
He may not be the finished product, but City are likely to have been encouraged by the progression that Denayer has made at Celtic and would be unlikely to have any qualms about sending another of their top prospects to the Scottish champions.
It means that it is a transfer which makes a lot of sense, and Rekik should be made Celtic's back-up plan in case they cannot negotiate a deal for Denayer.
