Manchester City defender Jason Denayer is reportedly a summer transfer target of Ajax head coach Frank de Boer.
The 19-year-old linked up with Celtic on a season-long loan basis back in August.
His performances in the Scottish Premiership have alerted De Boer, who has sent scouts to watch the Belgium Under-21 international in action over recent weeks, according to the Scottish Sun.
It is also believed that Celtic boss Ronny Deila is keen to extend Denayer's stint at Parkhead into the 2015-16 campaign, with City manager Manuel Pellegrini open to the prospect of loaning the centre-back out again.
