Sometimes, you just have their number. Like Jurgen Klopp against Pep Guardiola, Arsene Wenger and Spurs or Lionel Messi and pretty much anyone, there is something to be said for certain teams and players being able to beat a particular opponent time and time again.
And in MLS right now, the team that is presently enjoying the best season in the history of the league simply cannot beat their noisy neighbours.
Los Angeles FC are in the process of breaking all sorts of records. Carlos Vela is having the best individual season of all time.
