Had to look this one up...
We beat Bolton 3-2 in a replay in 1949-50 when we were 2nd Division and they were 1st Division. And then winning 1-0 at Man Utd in 09/10 when we were in League One.
Some stats on Leeds vs other large teams in the Championship:
2009/2010 Newcastle 3170
2010/2011 Leeds 3484
2011/2012 Leeds 2896 West Ham 2792
2012/2013 Leeds 2678
2013/2014 Leeds 3045
2014/2015 Leeds 2774
2015/2016 Leeds 3204 (As of Jan 4th)
Other than 10/11, we've been bottom half. Newcastle...
Still images show nothing and it definitely didn't hit him in the face.
I can't post links but if you look on @WALMOT3 's Twitter page, there's a couple of vine's that suggest it was the arm/shoulder but one angle is from behind the keeper and it looks a clear handball.
