The more I watch the sending off incident the more it looks to me as if Young went in with both feet off the ground and at least one set of studs showing. From what I recall the laws say that's a red card offence, regardless of whether the ball is won or not.
We're starting to get a decent core and spine to the squad with some decent players in Benteke, Delph, Sanchez, Vlaar, Okore and Guzan, as well as the resurgent Hutton. Problems are that too many of the rest are average at best, and at least two, maybe three of the aforementioned are likely to be off in the not too distant future. Shame.
