Manchester United will reportedly have a scout at the Old Firm derby between Celtic and Rangers on Sunday to cast an eye over Hoops star Kieran Tierney.
Per the Daily Mail's Jack Gaughan, the Red Devils have long been linked with the Scottish left-back, and manager Jose Mourinho's visit to Hampden Park for Scotland's friendly with Costa Rica last month was arranged so he could watch the 20-year-old.
Tierney missed the match through injury, but United are set to watch him again in Celtic's Scottish Cup semi-final clash with Rangers.
