@tzxsean,
tl:dr dude
But I think the question is about how La Liga teams play differently against RM and Barca right?
My opinion is yes, I think LL teams this season has put up better fights against us than against Madrid. Especially away from home, Barca have been made to work doubly hard to gain even a draw, even harder than how RM and MU made us.
But I don't think that's because the opponents tried harder against us, and laid dead against RM. I think that's kinda too simplistic.
IMO LL teams are generally too slow against a fast counterattacking teams. Take Valencia, so called the best of the rest, for example. They've done brilliantly against us. But when they played Chelsea at SB, they couldn't replicate that performance. That's because Chelsea was set out to play defensively, completely isolated Soldado upfront, and hit on the counterattack through Drogba. Valencia also struggled against RM at Mestalla. Well RM didn't exactly play counterattacking, as Valencia themselves tried to play contain football at the back, but RM's pacey players really unsettled them.
However, because they play at slower pace, they have better tactical nous. So when they are up against us, they tend to play better because firstly they've learnt pretty well from experience, and secondly because we also used to play at slow pace, which fit our opponents rather well. As a result, not only LL opponents can contain our tactics, they even get to play their own possession football against ours.
So why a fast RM team still find it difficult to contain Barca's slow paced style? Its because Barca's tactical nous is so much superior than other LL teams, that pace alone is not sufficient to beat Barca. Current RM team need better tactical skills in their squad in order to compete with Barca on the pitch. RM hasn't really learned from experience as good as other LL teams. The same can be said about MU and Arsenal.
So yeah, it is a case of the ball being round. A tactic may defeat this team easily, but may struggle against other. The same can be said about tiki-taka. But I still prefer tiki-taka much more than other tactics. So far it has serve us really well by completely conquering sides like RM and Man Utd, both are among the best club sides in recent years.
