Why do you think that Barcelona need good defenders? Barcelona conceded 5 goals in 14 games, this is the best defense in La Liga.
You are right, Barcelona are the strongest team right now in Laliga and their defense is very good with only 5 goals conceded in 14 matches. They are also the team with the lowest goals conceded so far compared to other teams in all the top leagues like Premier League, Serie A, Bundesliga, Ligue 1. I admit it.
They are followed by Betis in this indicator, they conceded 12 goals, do you understand how reliable Barcelona's defense is? Their attack also shares a leading position with Real, they scored 33 goals in 14 matches, they are doing great. There are still financial problems, but gradually they will be able to solve them, they also have a good bench, maybe Xavi just needs more time.
People need to admit Barcelona is better now but maybe people continue to cover up the facts because of their hatred for Barcelona. Of course this is not a good yardstick for analysis, these statistics are very important for gamblers rather than just judging from the outside and luck.
I doubt if Barcelona need more defender's what's needed is for Barcelona to find a good replacement for Gerrard Pique, They have a replacement but then they need a back up player since he left already after taking his decision about hanging his boot.
I'd lie if Xavi Hernandez hasn't improved the midfielder's and defender's how to give those passes in between the lines and key good ball possession.
The American Dest had a good game in the FIFA World Cup I'd appreciate if Xavi Hernandez can work with him well to fill in that right wing back role very well.
The frank about the defending arguments, Barcelona and Xavi Hernandez are doing great, all that matters if for him to win the La Liga as results is all that matters at this stage.
