Already From the beginning of the season I strongly have this believe that Barcelona will likely be this season's La Liga Champions despite that Real Madrid was at some point toping the league. This results has clearly shown that Xavi made a good signing during the transfer market. Having Barcelona got this 8 points clear ahead their major contender Real Madrid, is something that Real Madrid will definitely find very difficult to close the gap at this point in time in the league.
It is difficult to close the gap of 8 points. But it is not impossible. Still each team will play 16 matches. And Barcelona are also likely to lose points. Barcelona have to play very carefully in every match. If Barcelona lose the truck at this moment then winning the title will not be possible for Barcelona.
The performance of Barcelona players against Cadiz was very good. Especially in this match Lewandowski's performance was quite good also Sergi Roberto scored a goal and an assist. Also, Barcelona's defense was very effective in this match.
Barcelona are still consistently performing this season, only in European competition they have had bad results but in the league Barca only lost once to Real but after that they always won a point, either one point or a full point, that's why they can have an 8 point advantage, if they stay consistent then Barca will win this season and next week they will only face Almeira, the bottom team with more defeats than draws or wins which may be degraded, so Barca will again add points.
