2) Leganes’ attacking play cost them
What Alaves did so well against Barcelona last week was stopping Barcelona from playing, Yes they didn't have their biggest stars from the off, but they managed to keep their shape even after Messi had come on.
Leganes should have taken a leaf from their book and try to stop Barca from playing. Yes, they were at home and maybe an attacking approach is understandable, given Barca’s susceptibility at the back.
But Enrique’s men are one of the best, if not the best in the world on the counterattack. There is no substitute for a solid defence in the game and if Leganes had used a smarter approach to the game they might have nicked a point.
At the end of the day, goal difference does not play a major role in La Liga. It will all come down to the head to head record, but this is a harsh lesson learnt.
