ARSENAL newbie Kieran Tierney looks set for a Premier League baptism of fire against Manchester United tonight.
The left-back is finally fit and ready to make his league debut after his £25million summer transfer from Celtic this summer.
Tierney, 22, played 90 minutes of the 5-0 Carabao Cup thrashing of Nottingham Forest on Tuesday.
But he should expect a tougher test at Old Trafford, against a United side desperate to put their poor form to bed.
Playing alongside him in defence will likely be Ainsley Maitland-Niles, Sokratis and David Luiz, with Bernd Leno in goal.
Tierney's fellow full-back, Hector Bellerin, played the whole game of Arsenal Under-23s' 2-2 draw with Borehamwood on Saturday, bagging a classy assist to set up the equaliser.
New captain Granit Xhaka is set to anchor the midfield with Matteo Guendouzi, Dani Ceballos and Joe Willock playing around him.
Nicolas Pepe and Pierre-Emerick Aubameyang are set to get the nod up front in the absence of the injured Alexandre Lacazette.
Rob Holding is set to return to United for the first time since suffering a cruciate ligament injury there last December.
While he is unlikely to start, the defender is looking for closure by returning to the scene of the crime.
He said: "It will be coming full circle.
"Even if I am on the bench it will be brilliant to just walk back to that spot that it happened and just sort of take it in and have a bit of a moment.

"Then it will be business as usual. But I couldn't really write it any better.
"I suppose you could say it is a bit of closure for it to happen there and then your first game involved is back there. It will be interesting, but I look forward to it."
United, meanwhile, look set to start Mason Greenwood up front in their predicted line-up.
