The defender has been on loan at Tannadice since March in an attempt to get the first team games he wasn’t getting at Celtic.
And that’s what he has managed to do, appearing 13 times before tonight’s clash with Livingston.
As they finished third in the Championship table, United had to beat Dunfermline in the quarter-final first before taking on Livi, who finished second, for a spot in the final against the Premiership’s second-bottom side.
But they’re right up against it after losing 3-2 in a very entertaining match.
There won’t be many positives for Csaba Laszlo on a night where he also lost Willo Flood to a stupid red card, but Ralston’s performance was superb – and those watching with social media noticed:
Livvi now 3-2 up. Cracking game. Ralston playing well for the Arabs.

He’s never really impressed me but Ralston has been the best player on the park

Anthony Ralston is a crackin player at the age of 19, future is bright for him and clearly too good for championship level 👍🏼

Livingston are fucking brutal. Good to see United figuring them out in the latter stages of the half. Ralston standout.

Great response from Utd.
Need to keep this tempo up and try and push on for more goals tonight.
Ralston has been class.

Ralston has a big future ahead of him. Rate him a lot

It might be my green specs that I can never take off but Ralston has been superb in this half. Been everywhere!

That’ll be great for Celtic fans to see given big things will be expected of Ralston when he returns to Celtic in the summer.
