Manchester United had scouts posted to check on Celtic midfielder Matt O'Riley this weekend.
Since moving from MK Dons for £1.5m in January, the 21 year-old has become a firm favourite at Parkhead.
Although appearing for England at youth levels, the Londoner has recently featured for Denmark U21, who he qualifies for through his mother.
Despite being a highly-rated youngster at Fulham, then-manager Scott Parker continually overlooked O'Riley, instead preferring to start his own brother-in-law Harry Arter in midfield.
