The result of the Barcelon-Cadiz game can already be guessed from the beginning. The extra three points are enough to make the gap again eight points. This makes Barcelona certainly more comfortable to concentrate in the Europa League. Of course, Cadiz cannot be confused with Man United but this victory makes Barcelona's players morel more and certainly more confident. Sergio Roberto and Lewandowski made two goals even Sergio Roberto made one assist for Lewandowski.
It's hard to find another team that can beat Barcelona in La Liga this season besides Real Madrid. Yes of course, Barcelona have only lost to Real Madrid so far in La Liga in the first El Clasico match at the Santiago Bernabéu. But then, Barcelona might be hard to beat at home which is known to be strong this season by anyone.
Currently Barcelona can really get their focus high on the Europa League following their first leg draw at Camp Nou against Manchester United. Barcelona will do whatever it takes in the second leg despite the loss of two talented young players. As of today, I believe Barcelona have a chance to qualify for the next round of the Europa League this season regardless of Manchester United playing at Old Trafford.
Yes, that's the point! actually, during this season Barcelona lost only one game while they played 22 games so far, and losing only one game means they are strong enough so there are not many teams they can beat Barcelona this season which means there is not enough chance for a team like Read Madrid when they are in the second position of the table and waiting for the Barcelona to lose some points and take their place this season in the league.
