Kieran Tierney was spotted in the Celtic end at the Scottish Cup semi-final on Sunday afternoon. The Arsenal defender's old club faced arch rivals Rangers at Hampden Park, but an extra-time own goal from Carl Starfelt condemned The Hoops to a 2-1 defeat.
Celtic took the lead in the 64th minute through Greg Taylor, but it didn't last long as Scott Arfield equalised 12 minutes from time. Starfelt's own-goal in extra time gave Rangers - who went into the clash fresh off of qualifying for the Europa League semi-final on Thursday night - victory.
A fair few familiar faces were in attendance, with Tierney being one of them. The Arsenal star - who looks in line to be the club's next permanent captain if Alexandre Lacazette departs in the summer as expected - is currently sidelined as a result of a knee injury that will keep him out until next season.
