I have an English friend and he is a Spurs fan so I cheer for them as well. I thought that the handball call was weak, but from an angle it does look like the ball goes off his upper arm and that he swung his arm at it, that is a stretch though. The refereeing is similar to Basketball where a lot of calls, to my untrained eye, could go either way. I played soccer growing up and we were definitely not allowed to be physical like they are in the Premier League. I also don't remember that it had to be intentionally played by your arm/hand to be a foul, but I didn't play at a high level.
The play that stuck out to me was Lamela's run. The Spurs are a fun team to watch, and the fact the team is so young is really cool.
