More so than Burnley and Everton and Sheffield? I think your take is wrong. If teams in the CL treat us like they do, the refs will dish out a dozen yellows, and I'd be happy to have to play against ten men a lot more
Domestic games are always gonna be a tackle fest especially against the team you mention. They might take it up a notch just because they are playing the european champs. So you are right in saying it is not gonna be easier domestically.
What i should have mention that in proportion we can expect more % of our games in europe to be physical compared to the previous seasons (when compared to the premier league). We should not be expecting slower, tactical games like before as european teams are gonna come at us. It is just something we have to live with if we wanna create a dynasty in europe.
This is where we have to learn. I am not advocating that we dive and all that, but when teams start practicing their dark arts on us, we have to "ensure" that the referee has no choice but to card the opposition players early. Madrid are good in this....and we have to learn a wee bit from them.
We cannot rely on the refs to take stuff into their hands in europe. We either dish the same treatment back to their players or we "real madrid" a little bit.
