I suppose they will take a look on what happened there and will improve it, so again, I believe that Real Madrid should start the game with the spirit that they are facing a furious team, not the one that failed against Inter.
If you look at Barcelona's performance against Inter today, it is quite balanced if in the end they are directly met with Real Madrid. The most anticipated match in La Liga. Both clubs have been pretty good so far even though Barcelona was unlucky against Inter. Xavi's focus is still on La Liga, he realizes that their current quality is still not ideal in the Champions League. The return of Franky De Jong and Kunde added to Barcelona's power. Despite playing at home to the opponent I hope that Xavi does not waste the chance to decide who deserves to lead at the top of the table.
Their chances in the Champions League have now thinned out and maybe it was just a miracle that they qualified for the next phase and this means they will definitely suffer another financial loss due to failing in the group phase. The only hope is La Liga now as they clearly need at least one trophy this season.
With this they must step on the gas from now on, especially if there is a possibility that Madrid's mainstay defender, Rudiger, will also be absent in this match, so Barcelona clearly must be determined to win.
