Celtic bounced back from their torrid lose to Molde by hammering Dundee United 5-0 at Celtic Park on Sunday afternoon, opening up a four point gap at the top of the Scottish Premiership.
After that awful 3-1 loss to Molde in the Europa League, under-pressure boss Ronny Deila needed a big victory, and that's just what he got.
Leigh Griffiths got the ball rolling in the 23rd minute, before goals from Dedryck Boyata and Kris Commons added goals to make it 3-0 before half time.
Commons then got his second and Celtic's fourth shortly after the interval, and an Aaron Kuhl own goal ended the game late on.
A number of players produced impressive displays, but left back Kieran Tierney was arguably the man of the match after another superb performance.
The 18-year-old defender has been handed a first-team role this season, coming in for veteran Emilio Izaguirre on a number of occasions this term.
The Celtic youth product has shown his potential so far under Deila, and fans have now taken to Twitter to discuss his performance against Dundee United.
Many felt that he was the best player on the pitch, and called for Deila to make a permanent change at left back, with some believing that Tierney is now better than Izaguirre.
Here are some of the reactions on Twitter from Celtic fans after Tierney's performance against Dundee United...

Young Tierney deservedly Man of the Match today (only born Celtic fan on the pitch). Great energy & recovers well if he loses the ball HH— matt mcglone (@MattMcGlone9) October 25, 2015
Kieran Tierney fantastic today, hope he's going to be ahead of Izzaguire now— PJ McBride (@PJMcBrideCFC) October 25, 2015
Surely time Izaguirre got a nice long 'rest' and young Tierney given an extended run of games now.— Joe McGowan (@Gowzer7) October 25, 2015
Young Tierney looking very decent. Much better quality of crossing & final ball in forward areas. Izzy could be out for a long time— David Farrell (@davidfarrellfaz) October 25, 2015
Tierney WILL make mistakes & show inexperience at times, but he certainly has the potential to cement the left back spot for years to come.— David Brockett (@DavidBrockett) October 25, 2015
Young Tierney will have a bad game at some point but already proved in four games he's more than worthy of a proper run in the team.— Christian Wulff (@aHellofaBeating) October 25, 2015
