MADRID, Sept. 27 -- Although there are still three games to play in Spain's matchday 6, the past two days of Liga Santander action have already left supporters with plenty to think about as both FC Barcelona and Real Madrid slipped to defeat and the race for the title got a lot more interesting. Here are some things we have learned over the past 48 hours.

1. Valverde right to resist rotating squad

One of the criticisms leveled at FC Barcelona coach Ernesto Valverde is his reluctance to rotate his squad at busy periods in the fixture calendar running the risk of key players becoming burned out as they were in last year's Champions League quarterfinal against Roma.

Seven games in three weeks has left Valverde few alternatives other than to switch things around in his last two matches and the result has been 2 points dropped at home to Girona and a defeat to bottom of the table Leganes in games where fringe players again failed to shine.

It looks as if the summer transfers have failed to add the depth Valverde wants.

2. Real Madrid show weaknesses

So far it has been a relatively positive start for new Real Madrid coach. Julen Lopetegui, but his side wasted the chance to overtake Barcelona at top of the table on Wednesday when they were totally outplayed by Sevilla and lost 3-0.

Sevilla boss Pablo Machin used three central defenders and two wing backs, with Jesus Navas setting up the first two goals after getting behind Madrid left back Marcelo and Madrid were never able to get into the game in attack, while they were undone in defense.
