5 reasons why Barcelona lead Real Madrid by 19 points in La Liga

#2 Watertight defence at the back

Samuel Umtiti has played an important role in Barcelona's impressive backline this season

Ernesto Valverde has shaped this Barcelona defence into one to be reckoned with. They have been very diligent in safeguarding their goal this season. In 31 games played so far, Barcelona have kept 20 clean sheets, including 12 in La Liga.

They have conceded just 9 goals in La Liga all season, bettered only by Atletico Madrid's tally of 8, and they've amassed an impressive goal difference of +43. Notably, of all the league leaders amongst Europe's top 5 leagues, Barcelona have conceded the fewest goals.

With the inclusion of Yerry Mina, and Nelson Semedo and with Samuel Umtiti growing in stature and reputation, Barca's backline is moulding into quite a formidable force to be contended with.
