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.

The Gunners have struggled in his and Thomas Partey's absence, as they've gone onto lose their last three games against Crystal Palace, Brighton and Southampton respectively. The defeats mean that Arsenal have now slipped to sixth in the Premier League table, three points behind arch rivals Tottenham Hotspur in the all-important race for Champions League football.
Tierney will be desperate to get back playing again, but it looks as though he's recovering well following an operation on his knee just over a week ago. The scot took to Instagram to offer a slight update on the procedure, as well as to thank supporters for their support following the crushing blow that he will be out for the remainder of the season: "Op went well," he wrote. "Thank you so much for all of the messages of support. Really appreciate it."
