A late prediction from Rob Davies - 'I think that Reading have got know chance today and are going to ship a lot of goals, I think that the final result will depend on how many city want to get. i'm going to say 4-1 man City.'
Blue santa hats and waterproof ponchos seems to be the chosen attire for many City fans this afternoon - it's a very grey, rainy one in the North-West.
The Royals can take heart from their recent record at City - they've won two and lost just one of the last four away league games there.
The last time these two sides met was in the FA Cup back in 2010-11 when Roberto Mancini's side triumphed 1-0 thanks to Micah Richards' winner. Hopefully we'll get a few more goals today.
City are looking to pile more woe on Brian McDermott's men as they bid to close the gap on Manchester United - six points clear at the top of the Premier League.
The Royals enter this one in desperate need of a win having lost their last six, with their latest setback coming when they suffered a 5-2 defeat at home to Arsenal on Monday night.
Agree with Cian and think City are going to stroll this one? Or can Reading pull off a Christmas upset? There's still plenty of time to get in touch - Tweet me @SkySportsRachG or email firstname.lastname@example.org.
Cian Hughes has been in touch to say - 'Heya. tough game today, i think reading are not doing good,As for City, i think they are the strongest team coming out today especially because their at home, i predict a 4-1 win for City with: Yaya Toure (2) Tevez and Aguero/.'
On the Reading side of things, Jason Roberts misses out with a hip problem, but Jem Karacan and Jimmy Kebe make the starting XI after injury, while Danny Guthrie is on the bench.
Making his full City debut this afternoon is 18-year-old Karim Rekik, who steps in at left-back. The Dutch Under-19 international was on loan at Portsmouth last season.
There are a couple of big names missing from that City line-up as Mario Balotelli misses out with illness, while captain Vincent Kompany is on the bench with a groin problem.
Bottom side Reading will overcome odds of 16/1 if they can beat reigning Champions Man City (1/8) today, with even the draw considered an outside chance at 8/1. Sergio Aguero and Carlos Tevez both to score is 7/4, with City having won each of the 13 league games the pair have started together.
